I'm an encyclopedia addict — even in paper encyclopedias, I usually end up following links and just generally thumbing through, even when I just wanted to quickly look up some single entry.

As to interests and expertise: I'm interested in far more things than I'm an expert in. I hold an Engineering degree and an Sc.D. (both in Computer Science, to be precise), but most of my contributions here have been on other subjects. And that will probably remain that way.

I found that the nicest thing about Wikipedia is that I learn a lot when I write an article—which makes it so attractive for knowledge buffs like me. Well, at least if one stays away from the ridiculous battlefields of articles about (current and 20th century) politics, or religion, or quackery, or... it's far more fun to go write an article on a noncontroversial subject, e.g. the Teius teyou !
