Group Assignment

[rgardner]

Currently, groups are matched based on "interests," as defined as the union of their "skills I want to know" and "skills I do know." This is too little information for the classifier, which in random samples of 30 people (sample_data.rake) has led to only 3 groups of a possible 5.

We have a few options:

1. Groups based on custom weighting function (i.e. 60% similar want to know, 40% similar already know)
2. Admins pick group classification (put custom weights on want to know and already know).
3. Users can select their preferences

• but fall back on presets if not enough groups.
