Honestly man, all the forums that I've been to are either crappy, or are full of a lot of really pretentious assholes who think they are the God's gift to design. I have sometimes seen really good crit in the typophile forums. (www.typophile.com)
I also get my daily dose by looking at a couple websites that are updated pretty much daily:
welovetypography.com - daily pictures of interesting (not always good, but always interesting) type from all over the internet
cpluv.com - hit or miss. sometimes some cool stuff. Not a ton of design, but it's generally interesting.
prettyclever.tumblr.com - the blog of two graphic artists from chicago, updated with images of things they like daily.
underconsideration.com/brandnew - high profile rebranding critique. Read Armin's writeup, then read the comments. always interesting, but so many people post so fast there's no point in joining the conversation usually.
underconsideration.com/fpo - print only work. Lots of tacky wedding invites that offer really cool printing ideas. Gets you thinking about print design.
lovelypackage.com - exactly what the name implies; wonderful packaging.
I used to look at behance, but for every good portfolio on there there's about 20 mediocre ones. It's not a bad website, I just found myself turned off by a lot of the work in there.
There's a lot of bad design out there, and a ton of terrible information on the internet. If you want to learn about type, reading books is going to help you a lot more than seeking out info online.
I'll make some good book suggestions when I get back to my house this evening.
Hope that helps!
