The Best I Have Found

For the price range, this is the best aggregator plugin I have found. Most of the other plugins came with the most important features being locked unless you pay for a premium service. Tagboard, even at the free level, offers about every feature you will need. Pull in posts from nearly all available social network sites using a hashtag. For free you get one feed stream from which you can do all of the above. The posts load out to your page in a nice tile, gallery format. The styles are easily customized via CSS. If you do decide to upgrade, the prices are some of the lowest around.

Highly recommended.
