Yeah I got tired of parsing the cryptic messages on this and other threads too. I could not exactly follow if the idea was for us to or pay for the development or to do the development ourselves. Plus I was upset when I saw on 2 of our blogs that have over 100,000 Posts on each and about 10,000 tweets that somehow Twitter Tools placed all the Tweets in the Posts area.... I guess that happened during the initial upgrade process. Again, it was my fault for not testing it first -- but I had grown to trust the AK plugins.
So I deleted Twitter Tools and Social and instead am using NextScripts: Social Networks Auto-Poster. It is a fantastic plugin with lots of abilities, and I may upgrade to the paid version soon too.
I will monitor Twitter Tools and Social, and if they start having more functionality I want to also support AK and may add it back to some of the blogs we oversee.
