I have this suggestion below, let me know how it sounds -

• Users should be able authentication via github account alongside twitter.
• We will take github api permission for accessing there public repos and public activity.
• This public activity, taken from github will be shown on activity page of idea hub.
• It will show recent open source contributions by ideahub members.
• It will show all member profiles with
  • total number of open source commits member has made.
  • project wise details for how many commits made on which project. This helps decide whom should I concern if I have prob/something with a project. Kind of easy to see what's a persons major contribution goes to.
• We can also make list of top open source contributors. This will be weekly or monthly list. List will depend on no. of commits made in opensource. If this creates a healthy competition and some excitement to ideahub, I would love this feature.

Also, I feel, if we can make a rails engine to do above things, this can be used by other local ruby community sites as well.

What say ?
