Here's an idea for the community blog that could help to grow the audience, and draw attention to the site. A monthly UX angel service, with some kind of superhero theme.
- Choose a product (web site, software, smart phone, lava lamp, pen, car, space ship, etc)
- Do a UX review of the product (either focussed on a specific feature, or more broad)
- Make recommendations for improvements
- Do re-designs of certain components
- Write it all up in a beautiful blog post
Each article would probably require 4-5 UX'ers to participate. And there would need to be a style guide and/or writing guide to maintain consistency. The value to the recipient of this review could be estimated at $1-5k, so being selected could become some kind of competition, which offers opportunities to draw attention to the site and grow the community.
This would be a lot of work! but would be really cool.
