I ask myself this all the time.  I'm constantly changing.  Well, maybe that was me.  It feels like more recently I've been in a rut.  Maybe crashing my website ('cause I didn't want to figure out how to upgrade) was the best motivator for me.

There are several ways to find out who I am:

1. Check out my LinkedIn Profile.  While this really doesn't tell you who I am, it does give some basics about some of the things I've done to become who I am.
2. Do a web search.  I don't use Google any longer to search.  I'm a Duck Duck Go fan.  But whatever you use you'll find some stuff that I've done. I'm all over the place on the web.  I still find references to me being in old positions.  You'll find some old articles about me, about our board game collection, and I'm sure many broken links to stuff on my old web site.  Go beyond the first page.  Always in a search, go down multiple pages.
3. Facebook - Yup, I'm still on Facebook.  Lots of public posts.

I'll write more later about who I think I am.  But the above is a start at least for you.
