You may want to check out some of the more popular area-specific forums.
Views From The Top is more New England oriented and requires someone "sponsor" you before you can actually post...but you can read the forums without being a member.
ADK High Peaks Forum is more Adirondack (and to a lesser extent, Catskill) oriented, and doesn't require "sponsorship".
ADK Forum is Adirondack oriented, and is somewhat less hiker-specific, but still has lots of good info.
There's actually a "gathering" coming up near the High Peaks this coming weekend, and another one in Speculator, NY on 8/21, where you might be able to meet some people and make some contacts, if you were so inclined. Just a thought.
I spend most weekends in the Whites, but also get to the Adirondacks and the Catskills regularly, so feel free to PM me if you have any upcoming trips where you might like some company. I might be able to make some time.
