Browse groups by category
The group page under the “collaborate” menu has the capabilities of searching for a group or looking at a list of all the groups. It might be difficult to find groups of people with your same interests if you would like to browse the list. Would it be possible to create a “browse by category” section?
I am thinking about how I discover new apps for my phone. I browse the apps by category until something jumps at me. We could think go organize the groups by the most activity in each category.
Another idea is to recommend groups to a user based on his/her research interests, current groups, etc. Something similar to the “genius” feature in itunes or the recommendations that are found in amazon when one is browsing for a particular book.
