I was contacted today by someone who is a fellow microISV er.  He's actually launched a site and it looks pretty neat so far.

The site is connectviabooks.com.  It's a great site for meeting up with people who have the same interest in books as you.

Here's how they are marketing themselves:

Connect with people who love the same books as you do!
Ever read a great book and wanted to discuss it with someone?
Ever wanted to find people locally who like the same books as you do?
Find people who share your interests, your hobbies or just read the same books.

I've signed up (nickname 'unleadedsw') and created a couple of booklists.  I'll keep checking back on the site and seeing how things progress.
