Hey Lon- Great question and piece of feedback. We use FB login now, but the ratings (1-10) and descriptions are not captured by Facebook. Location and People tags could be if you use Facebook location or People selector, but you can also enter those manually or use Address Book. You can publish an individual rating to your Timeline, but that is totally optional (and not a default setting). We hope to have more means of authenticating in the future...this was a start.
The Philadelphia Self Quantifiers group brings together technologists, healthcare professionals and anyone interested in self-improvement through data gathering and analysis. We'll meet to discuss technologies and techniques that aid in understanding of the physical, mental and psychological.
As the group grows, we hope to have regular "show and tell" meetups in which members will share their quantified-self tools.
NOTE: This group is intended to replace the Quantified Self Philadelphia that seems to have abandoned by its creator. We hope the members of that group join us over here!
