You might, but I don't! Besides, I've written it up already. Read these:

Basically, the cost of "free" can be high. Sometimes it's too high.
Hmmm. So Wikia is a "commercial version" of Wiki... basically they "buy up" other noncommercial wikis, and then use that info on their site that presumably has ads, and other forms of revenue generation.
So in business laymans terms, Wikia provides a server(s), gathers information from users, has ads, and serves a somewhat useful service, albeit at the cost of "making money".
I had a service like that once. It was called Impulse. I bought Sins.. needed to install Impulse so I could buy the first expansion. Wasn't sold in stores by me... I tried to log on, it said username and password incorrect. I said.. interesting, I created account today... it doesn't work. Lemme try tomorrow. Didn't work for a couple days, so I never bought expansion over IMPULSE. I then bought trinity pack, and had to use impulse to get update. Tried making new account, it told me I already had one. I then typed old password/username and they worked. WHEEE!
Since then, I have had to use the service to install Elemental as my disks from the store wouldnt fully install. After getting it installed (and of course IMPULSE updating ITSELF, Impulse now sits on my toolbar as a reminder of how something that should be free (Wikis... updates for games you buy) is always gathering info about me and trying to sell me crap. I can think of at least 5 things that Impulse has spawned on me in last month or so to generate revenue.
So really I don't see a difference.
Wikia provides content (pages). Impulse does too (updates)
Wikia wants to gather private info about you. So does impulse
Wikia wants to make a buck. Impulse as well, of course
Wikia targets ads to me. Impulse targets ads as well, in the form of games to buy off their site.
Where exactly is the major difference?
Not trying to be a jerk here, but if Wikia is NOT WHAT people are used to on the web (ads, privacy issues...) then maybe they are using a different internet than I am.
For the record, I don't use Wikia, if it ain't on wikipedia or I can't google it, I don't need it.
I AM FORCED to use Impulse though. So I guess there is the difference????
