Yeah it will take off, but the discussion aspect may need work for certain communities (one example crafts, see crafster).
I can think of these sites I'd visit:
Car repairs/advice,
Graphic Design,
Business advice (freelanceswitch will probably be someone to approach),
Marketing,
Maths,
Food/Cooking/Recipes,
Cocktail Mixing
Sites that will work:
Crafts,
ESL,
Athlete/professionals training advice
The pricing will need to drop for smaller communities to make the port, and include a donations feature to help communities fund themselves.
