Really useful list, first one I’ve seen that lists by function! Thank you. Wanted to suggest another useful app we’ve been using in our PR business. http://www.MediaFunnel.com helps us efficiently coordinate our “group tweeting.” We have several people contributing to our business Twitter accounts — before MediaFunnel we’d write a tweet then email it to our account manager who would review and return for publishing. Now we all work from the same dashboard and love the editorial review function, brand monitoring, alerts, search, Salesforce integration (we can easily create a lead from a tweet then submit it to our Salesforce)… Much more! Also like the email, text & SMS submission functions. All in all a very solid service, easy to use and meets our business social media publishing needs. Anna E.
Thanks, Anna. I have added media Funnel to my A-Z Link Directory.
What a great resource!
This is a great list, my colleagues and I are about to launch a new Twitter tool in Beta which has a combination of features you can sign up for an invite here: http://www.tweasier.com
Thanks – I have bookmarked this page.

Hi, Nancy. I have 20 blogs and you can get the feed by clicking on the orange RSS symbol in the header of this blog. Thanks, Kathy
Good post, thanks for adding it. It was good to read on this rainy day!
