If you're part of a group or business that uses a blog, wiki, chat software, bug tracking, or other webapps to track progress, Flowdock wants to help you organise all that with a streamlined look and tag-based organising.
In other words, Flowdock wants to be the place where team members can check in and check out all the other things that have been happening across different sites. If a user or customer sent an email with a complaint or suggestion, you could paste it to Flowdock and tag it #complaint, and other members in your group can check out the #complaint tag section at any time. Copy-and-paste is not a means in itself, of course, so Flowdock also imports any manner of RSS feed you can throw it, along with importing Twitter feeds and searches and IMAP email accounts. Using a single-site browser tool like Fluid or Prism, you can easily make Flowdock into a desktop tool and notifier.
You could use Flowdock as a to-do organiser, a multi-feed watcher, or another team purpose—it all depends on what your small business or group wants to do with it. It's worth checking out to see if it might be more organised than mass-mailing copies of text to your co-workers. It's free to use, with no pricing plans in sight at the moment.
