Have you tried Aardvark? This looks very promising. Infact Google just bought it and made it part of Google lab.

Johannes I agree with you about the difficulty to follow tweets. Many people have a hate-love relationship with it. But the information are really valuable and often better than what you get elsewhere.

However, there is still great potential in microblogging in defined networks, like e.g. within your organization (if it is really big) through Yammer or any other corporately introduced microblogging feature, or within a particular community which has its own Twitter channel everyone is faithful to.

The contradiction is, that the larger my network is, it seems the less value I get out of it, while in my smaller and closed networks I get engaged in more frequent and direct feeback. Of course there is a treshold for which network sizes that is effective (and I haven’t figured out where that treshold is). And the problem remains that I miss out on a lot of information which is out there outside my closer network. But to a certain point, I just have to acknowledge that my brain has only limited capacity to digest all the data out there….
