Hi, I just discovered PearlTrees.
It's a way to organize and share websites.
Looks like a sophisticated 'graph theory' version of Facebook (or Twit).
My own account name on it is virttrees,
if you'd like to join too, that would be great. ☼
I've been doing so many projects at once lately that I haven't had
time to read it further.
