I'll just write some narcisistic stuff regarding myself around this Wikipedian world.
I've been reading these pages for about two years, but then again, I am not too knowledgeable or anything, so, mostly, I don't find anything I know about more than what is written already (and I hope I made sense with this sentence), and since doubt is my master, I really can't say I don't think of the possibility of me being wrong and the article right, when I think it's wrong. But anyways, recently I thought of modifying some of the articles I though to be wrong or too short with my short knowledge on editing them.
I don't start articles (althought I tried once, and this is my second attempt). I just like to fix what I think it's not right in the articles I read from time to time (so, I fix mispellings or typos most of the time). Sometimes I add some stuff I know or can find out about when I don't know it already, although, I only do this to articles about things I really care about (and really know or can find information about). When I modify something I think it's important, I always write on the talk page about why I modified it, so that if there's someone who knows better than me about it, he can prove me wrong and put it back as it was. The articles I mostly meddle with are Sci-fi related. Mostly, Videogame, Manga and Anime related.
And that's pretty much it. If you read this all... I'd really know why you did it... There are lots of more interesting things you could do here. Althought, not 100% reliable (as everything made by humans) as it is made by lots of people, it has a very nice and thick pillar of neutrality supporting it (Maybe you disagree, but I think this is true). Besides, you can add your wisdom to this place (If you have some it's not already here, of course, and you should know, there are still plenty of knowledge to be added).
