And you have millions of links out to spammy websites - mathematically - Wiki should have been banned a long time ago, unless human intervention did turned off filters.
And on another note - how would you feel if Dictionary was ranking in the top 10 for every word?!? I mean, the page will be 100% on topic, great content etc.
Wiki is just another half-arse website trying to dominate the Internet based purely on hype. There is maybe 1% true and usefull content on Wiki, and that's a fact.
