Spamming for prizes

If it's a user I recognize and have valued their threads/posts in the past, I'll be more likely to post in it.
If it's a thread about a topic that interests or concerns me, I'll be more likely to post in it.

I open threads mainly with the goal of inspiring friendly yet interesting discussions.

Or I post in threads to answer a question, like this one.

Depends on the topic and on the creator.

I stay clear from certain topics regarding some members here, as they add next to nothing in terms of healthy discussion and are just propaganda tools for their own agendas.

On the other hand, there are some members in here as well (Robotechheaven, Nen-suer, Crystalchild, Euphoria, MM and many others) in which I've come to expect quality threads from them as they're quality posters themselves.

And then, there's the random thread with a theme so WTF?, I just have to check it out

I come for the boobies.
This thread lacks.

I can tell you what makes me NOT click on a thread:

-If it's a topic that's been done to death
-If the thread title has absolutely no detail about what the thread will be about (and it ends in "......")
-If it's one of those "_______ has the best graphics" threads
-If it's a religion thread that really makes me think
-If the words "elimination game" are anywhere in the thread title
-If someone wants relationship advice

I tend to avoid these threads without a second thought. Threads that really attract me:
-any thread that bashes something I like
-any thread that talks about something I've experienced personally
-any "hot chicks" threads
-any thread where somebody needs help with something I know about
-any thread that makes me laugh just by looking at the title
- any thread that talks badly about Uncharted 3
-any "List your _____" threads
-any thread that shows excitement about something I'm personally excited about

If I already have a reply in my head when I read a threat title, that's a good thread. If I look at the thread title and I don't know what I'm getting into (in that ambiguous, they're trying to trick me into looking at their thread, kinda way) or any thread that I'm waaaay too familiar with, I avoid.

Only if it really makes me think......

The creator of the thread means absolutely nothing to me. The thread title can mean a lot in some instances but some topics are indeed done to death and are usually pretty shitty. I suppose my reasons for opening a thread probably vary mostly on my mood and at the end of the day, it's only a few minutes wasted if it's got nothing for you.
My routine when visiting the site is I hit my bookmarked MS forum then from there I hit the VGChartz tab at the top of the page, look that over for something new then scan the hot topics. Hot topics is the only thing that gets me to stray from posting exclusively in the MS forum. I also usually just read threads and don't post because a lot of the times what I would have posted has already been said or my natural reaction would be to say something offensive. I try to keep myself in check from being too rude because I see it as mostly a lose lose situation. Another thing that keeps me from posting is that I normally don't care to get into these drawn out exchanges with other posters, good or bad.

For the points!!!!

This. Also I like the occasional debate so if I see something I think is ridiculous or untrue I'll probably quote the guy.
