I've always been interested in Quantified Self, and have used homegrown spreadsheets to track my finances and miles run for many years. And now that apps are making this easier and easier I'm interested in tracking more and more metrics.
Are you collecting any personal data?
Yes - finances, miles run, and weight
Anything in particular you'd like to hear or learn about at meetups?
I'm generally interested in lifelogging / behavioral modification through tracking, etc
