I get to hear about Wikipedia a lot, working in a library. It's useful someties if you're trying to get a general idea about a broad topic. Much the same as with encyclopedias. Because of the nature of encyclopedias (and wikis), there is a higher chance of inaccuracy than with a dedicated source book. After all, in the
best scase scenario, the author of an entry is trying to cram a topic into as few words as possible to fill an allotted amount of space. It's easy for information to get garbled under these conditions. Kinda like this post...
In any case, that's why it's best to go straight to a dedicated source for information...like this forum! The folks here have an astounding amount of information and know-how.
And I think this post of mine has turned into exactly the sort of thing I was talking about.
