Well, IRC-galleria is one of the biggest places to meet Finns...
http://irc-galleria.net/ (Click "satunnainen" for a random profile and "yhteisöt" if you want to browse categories)
And this forum might be of interest, mostly foreigners post there but you can find Finns there as well, of course:
http://www.finlandforum.org/bb/
In the "Kielikoulu" forum you can discuss the Finnish language.
Toivottavasti tämä auttaa :)
