Of course many here seem uninpressed because they don't know if it is gold or silver etc but seriously is nice to see over half your userbase is some how connected. Also only reason you need gold is to play online so silver still gets many of the features gold has so it is still an important number. Think of it purely as a social network and 10 million is very nice for MS especially since they met their goal 6 months in advanced. Those silver users that nobody seems to care about may still spend money on xbox live arcade games and the market place etc. Some may buy 1 month 3 month cards etc for when they want to go online etc.
Finally what do you want to compare xbox live to in order to be impressed? I am sure the psn has a number of users as well maybe close to MS at around 50% but similar how many of them are playing online? Does it really matter? Both services have millions of users with MS having a nice percentage of that paying. Vgchartz doesn't track xbox live 12+1 month card sales but if they did I am sure it would be a top seller every year. What company wouldn't want an extra $40-60 annualy from a number of users. It would be nice to know a percentage of how many are gold but if I where to go based on my friends it has to high with the top selling 360 games like gears, halo, cod4, rainbow six all having great online experiences. I am sure many will continue to be uninpressed though would be nice to know something besides well how many are gold users etc. If it helps I been a gold user since I bought my system in 2006 so there is at least 1 person out of those 10 million who has gold :)
Quick poll: How many 360 owners here in vgchartz have xbox live gold or have ever had it?
