They've actually been stagnating for years, and I think our overall active userbase (ie, people who post) has shrunken over the last two years. Looking at darth's E311 thread from last month, the official threads for each conference had considerably less posts and views than their predecessors over the previous 1-2 years. The drop off in views was relatively much larger than that of posts, implying that lurkers are leaving in much largers numbers than posters. And this is despite new hardware being shown at two of the three major conferences. In comparison, neogaf broke its peak userbase by several thousand users (members + guests) during Nintendo's conference this past E3.
Why is our userbase not growing? I would say there are two causes:
1. The current userbase is not creating the type of interesting discussion that would draw in new users.
2. The current forum structure (rather, the number of boards and the topics they cover) is confusing and unnecessarily convoluted, intimidating new users who are unfamiliar with the site. As well as annoying certain older users. *raises hand*
The first issue is rather tricky to address, and would probably involve a lot of arguing that will get us nowhere. In fact, I've attempted to address it on the staff forums in the past, to little effect (though my opinion on the matter has evolved considerably since that time, which makes me better understand how people can disagree significantly on the matter).
The second issue can be easily explained and fixed. We have too many boards, especially given the rather low traffic of this site, and that leads to redundancy and confusion. For any users just coming to the site, it's a matter of "where do I go" + "that's a lot of clicks". In the grand scheme of things, those are little issues, but in website design? They're huge. It's these things that keep the casual browser from becoming a more dedicated user. They're just not gonna bother if they don't already have a vested interest in the site (hence why a higher percentage of lurkers have disappeared than posters).
To focus specifically on the redundancy of the boards, let's consider a thread about Windows 8 beta screenshots. Should it go in off topic? After all, it has nothing directly to do with gaming. Should it go in PC Discussion? PC gamers are the ones that'll primarily be affected by a new OS. Or should it go in Microsoft discussion? Microsoft does make Windows, so that would also make sense. For a more recent example, there's this thread about Samsung TVs getting posted in Sony discussion, simply because they're competing with Sony. This redundancy creates confusion for both those making such threads, and more importantly for those trying to find such threads.
On a certain other forum, the location of such a thread is very obvious. Does the topic involve gaming features of Windows 8? If yes, put it in Gaming Discussion. If no, put it in Off Topic. You're not forced to click though several boards to find what you're looking for. You know exactly where it will be.
Even if the layout of the forum were made more clear, the number of boards is still unnecessary. The Off Topic section has been broken up into six separate boards, despite the old off topic board being one of the slower on the site. Of the new boards, the Movie Discussion board is the most active, yet on average only 1-2 threads see new posts per day. It would be easy to find these threads on the front page of the old Off Topic board. The second most active board is the Politics board, which has threads an entire month old sitting on the first page. This does little to make new political threads easier to find, and it only encourages thread necromancy. In fact, it probably makes new threads harder to find, given anyone interested in new off topic topics must now click through multiple boards to find the information they could've found on a single page previously.
And then there's the Latest Charts board. For the first month people were still posting charts in General Sales discussion. I really can't think of any reason why they're now on their own little board. At least no reason that outweighs the convenience of having them together with other sales topics.
Now, one could say the Hot Topics section addresses these problems, but it really doesn't. With the Hot Topics section, you have two options:
1. Have all boards active at once, creating an avalanche of new threads with every refresh. That just doesn't work.
2. Edit the Hot Topics section every time you wish to view a new set of boards. This takes as much time as clicking through each individual board, plus it's a foreign and intimidating idea for people coming over from other forums. Really, just add up the clicks. One click to show your filters, a couple of clicks to edit, another click to save filters and refresh. Compare that to hitting the Forum Index tab and clicking a new forum.
In order to make the forums easier to browse and more inviting to new users, I would recommend combining everything into four main boards:
Gaming
Sales
Website
Off Topic
With maybe an additional community/online forum for our online gaming communites/clans, whose threads can last months/years. This way you always know exactly where to post or find a topic, and this structure significantly decreases the total number of boards you'd have to browse to find all the latest topics.
Even if some insist on keeping individual boards for Nintendo, Sony, Microsoft, and PC gaming (which is really only useful for those who heavily favor certain platforms), I think it should be made very clear that these boards are meant strictly for gaming discussion. Maybe change them to Nintendo, PlayStation, and Xbox or something. Everything else should go in Off Topic.
Now, one could say, "Well, GameSpot, IGN, and Gametrailers all do it just like we do!" However, they're stagnating too. Only one major gaming forum is showing significant year on year growth. This is the internet, an invention that allows us to access an unquantifiable amount of information while sitting on our asses and barely moving our arms. In the end, the one who makes this process the quickest and easiest wins, and it's clear who's winning. It's not us.
By the way, hatmoza signed up for gaf yesterday (and now he waits, muwahaha). I'll try to get him to post in this thread, given we've discussed this topic a lot on IM, but he said he currently isn't planning on coming back. However, he and others I've talked to have mentioned that changes like the above would make posting on this site much more enticing than it is now.
So what do YOU guys think is causing this negative growth, and how would you propose fixing it?
