Twitter?

I have nothing to tweet! For the past three hours I have been immersed in Google Reader, absorbing articles about the libraries of today (more like a kitchen than a grocery store was one interesting comment), the technology of today and the opinions of seemingly everyone in any related profession about both. And then I became engrossed in a feminism thread (Madonna yesterday, Lady GaGa today), and a cabbie blog before deciding that I really should try and find my log-in details for an old Twitter account, long forgotten, now revived- Finestrino. . .
I am now following several information professionals but so far their tweets are strangely similar to the what are you doing now strand of Facebook. Only a few of those I am following have tweeted anything of professional interest- eg. Librarything and RTennant are both worthy tweeters. Links to articles of interest seem to be the most useful tweets and this is where tweeting could come into its own as an information dissemination service in 140 characters.
The problem I have is that there are so many posts I feel like I have to be logged in every minute to not miss an interesting tweet amongst all the mundane postings. And amongst all these thoughts is the realisation that the professional association I work for is not using Twitter to its full potential. We could be doing so much more for our members through Twitter, linking them to their colleagues, informing them of professional developments, academic articles, upcoming events, the list goes on! But do I have this dedication? And what can I tweet on behalf of myself that will not be put in someone's mundane folder?
