Whether you think the whole microblogging phenomenon--encapsulated by Twitter--is the wave of the future or a useless tool soon to collapse under its own weight, one thing's for sure: It hasn't exactly been a major cash-generator.

Microsoft and Twitter have been trying show a path to revenue generation, though, with ExecTweets, a site sponsored by Microsoft (for an undisclosed sum) and designed to push 140-character-or-less "tweets" from some of the nation's most prominent executives to Twitter users.

Built by Federated Media and originally launched in March, ExecTweets (now with 1,134,160 followers) is just one of the ways that Twitter has been gradually integrating itself into enterprise life; Salesforce.com has been adding Twitter to its Service Cloud, and other companies have been exploring ways to use the microblogging service to monitor the adoption and discussion of products and services in real time.

Over the weekend, ExecTweets got a little more granular with the introduction of ExecTweets IT, a version of ExecTweets targeted at the IT pro community. Hot IT topics include Business Processes, Cloud Computing, Collaboration, Communications, Desktop Optimization, Mobility and Open Source.

It may not be a huge revenue generator for Twitter or Microsoft, but for IT pros, it could be worth checking out to see what your brethren have on their collective mind at this exact moment.
