It's a bit more reliable than Wikipedia on some aspects, that's for sure! It's also quite fun to browse once in a while.

I love Tv Tropes and the Other Wiki, but they both have their faults. I honestly wish Tv Tropes had a bit more structure, like Wikipedia, like requiring Trope pages to explain where the name comes from, which many, maybe most, of them don't do.

Oh yea. TV Tropes indeed will ruin your life. One moment you're looking at the Page for "Big Bad" then the next you're looking at "Older than Feudalism". There is something about it that makes it so addictive.

Until they changed their format to what it is currently, it was what I read and read and read. Now it's Reddit, and occasionally TFW, but it was TVTropes for a long time.
