Thanks Kim! It's always great to read what is available and see if I can apply the apps.
The list includes using twitter from Aweber, which I use for a client. It's a good one and clients love it.
I noticed the other day that there is also a Yahoo plugin for messenger as well. (In messenger, there's an Add Plugins called Twittersync which takes twitterers to a page to download the app.) I haven't tried that one yet.
Also, if you are a REVA or work with real estate clients that have an ActiveRain blog (before they started a fee-based service), there's a twitter feature there as well which sends out blog links from there.
