A number of Acrobat team members use Twitter as another way to interact with the community about what's going on with Adobe Acrobat and Adobe Reader. (If you're not familiar with Twitter, you can think of it as a "micro-blog", where authors can provide short 140-character blasts telling you what the latest is.)
Here are some of the Acrobat team members who use Twitter to discuss Acrobat. Feel free to follow and engage us. If you know of other Acrobat, Reader or PDF focused Twitter feeds, please leave us a comment.
