Attention TrendSlate readers, we have 5 beta invites for Brizzly, the service we recently covered as a must-have application for Twitter. Click here to access the private sign-in page. The invites will likely go quickly, so if any of you have (or need) more invites, then post in the comments below.

As we mentioned previously, Brizzly is built by Jason Shellen and other Google Reader team members. We believe it provides a better user interface than Twitter. You can manage multiple Twitter accounts through one interface and easily toggle between them, save searches, and add profiles to groups.

At TrendSlate, we communicate with various venture-capital firms & entrepreneurs across Southern California, and Brizzly is essential to the work we do.
