Something that really helps the project is positive reviews in the right places. If you have a few minutes, take some time to write a brief review of the release both here and on NuGet:
Even if you don't have time to write something, go ahead and give it 5 stars :) It's just a click.
If you are feeling really ambitious....feel free to send email to people like Scott Guthrie, Tim Sneath and members of the Silverlight, WPF and WP7 teams to alert them of your positive experiences. That helps Microsoft understand better how developers are
using their platform and what types of things make development easier and more enjoyable.
