Hi HN,
My friend and I created ThreeAbout.me this weekend as a great way to condense your accomplishments into three easy to understand sentences. An online resume or business card of sorts that you can be proud of and is easy to consume.
The inspiration for the service came from our experiences networking with people that we didn't know anything about. What if they just told us the three things we should know them for?
We also wanted to experiment with reducing signup investment (no passwords, for example).
On the technical side, ThreeAbout.me was written in Python and Django. We use Postgresql for storing aggregated signups but everything else is stored in Redis. Would I use redis again as a replacement for an RDBMS? Probably not, so I'm curious to hear if others had different experiences.
We hope you enjoy it!
