Are you looking for ways to improve your productivity in social media? Do you want to make Twitter more efficient or even automated (to a degree)? SocialOomph is a freemium-based tool that helps manage multiple Twitter accounts.
There are several useful features, but the one I found most useful was the ability to track key words or industry specific words, key phrases, or hashtags. Other key features include the ability to schedule tweets, auto-follow, direct message inbox cleanup, and vetting new followers between accounts.
The downside is that I found the site a little challenging to navigate. The free version has plenty of options for managing twitter accounts, but the paid version provides support for LinkedIn, Facebook, Plurk, and various blog sites. I plan to try other similar tools such as Hootsuite, Buffer, and TweetDeck before committing to paying for the premium service.
