Of course, I use email (mgalloy at gmail dot com) and instant messaging (mgalloy at mac dot com). There are a couple other ways to stay in touch with me though.
Twitter is kind of like RSS for instant messaging. I've add [my Twitter messages](http://twitter.com/mgalloy) to the sidebar. They're not very visible right now, but I'm planning to re-organize the site soon to make them a bit more prominent. Of course, if you use Twitter, just check me out there.
Especially if you were my student back when I was teaching IDL or have otherwise worked with me, I have a [LinkedIn profile](http://linkedin.com/in/mgalloy).
Also, check out the project sites for [IDLdoc](http://idldoc.idldev.com) and [mgunit](http://mgunit.idldev.com). There is a user [mailing list](http://lists.idldev.com/listinfo.cgi/idldoc-idldev.com) for IDLdoc.
Feel free to introduce yourself!
