I've been twittering (tweeting? I'm still not sure) for more than a year under mpolino. I've recently started adding Dynamics GP content as well as personal content. All of my GP content will be marked with a tag that looks like this #DynGP. This makes it easy to search and find Dynamics GP content. I'm working to try to make this a consistent tag among Twitterers to make it easy to find GP related content across Twitter.
Twitter won't replace blogging, but it is a nice, fast supplement to it.
