Ask HN: How do you inform users of new features?

Interesting subject. I just finish posting about a new feature 5mn ago 1. I write a blog post about the new feature (http://blog.snapabug.com) 2. I send a link to the post through our Twitter (@snapabug) 3. I send a link to the post from our Facebook Fan Page. I will then later, add this new feature description to our monthly email newsletter. I'd be curious to know how others do it too.

At Arktan, we do the following, 1. Write a blog post describing the new feature. 2. Send a message using our internal messaging feature with a link to the blog post. 3. Send out a tweet with a link to the blog post.

We have built a notification system, we are not using it yet, but we are going to use it for announcements.

on our site we have an "announcements" section on the profile page (first page user sees when they sign in) so we can post something there. We usually will like the announcement to a longer story (similar to a blog post) where users can comment and provide feedback. We also have public feedback groups on our site, so we'll often post the updates there as well as let some of the more active users know directly. - Julio from Experience Project (http://experienceproject.com)

Besides the normal stuff (newsletter, blog post, etc), I e-mail current evangelist users directly and ask them to spread the word.
