Count me as a vote against. I much rather check in one place (Mail.app) than on a bunch of web pages, all with a different (and often annoying) UI.
Mail is where I want stuff that's sent TO ME.
The web is where I want large repositories of useful information I may or may not be interested in.
Forums can let you be notified by email of responses to a thread. (Oddly enough, Nabble does this by default which gets me two copies of everything in my mailbox until I turn it off.)
I regularly visit about five different forums and infrequently visit about thirty others. If this were all mailing lists, just deleting crap would be a full-time job. I actually have junk mail filters automatically deleting crap from old mailing lists I can't seem to unsubscribe to.
