Twitter: waste of time or worth it?

Back in March, at the start of UKSG's annual conference, Todd Carpenter of NISO wrote this interesting LiveSerials posting about Twitter and how it is used during conferences.

Today this subject is raised again by CrossRef's Kirsty Meddings, writing the editorial in the latest edition of Serials-eNews, UKSG's news bulletin. (Note that access to Serials-eNews is usually an exclusive benefit for UKSG members but all being well you should get access to this article by following this link - let us know if you have any problems!).

Both pieces are useful in helping to explain why Twitter is gaining such traction in our community, and both are generally in favour of Twitter as a channel for sharing resources and building relationships during conferences. Do you agree? what about using Twitter outside of the conference centre - are publishers, libraries and others in our sector putting it to good use, or wasting their time?

UKSG has set up its own Twitter channel, @uksg, and encouraged usage of the #uksg09 hashtag during the conference. Are we right to be exploring this medium? What more could or should we be doing? We're interested to know your thoughts so please do discuss via comments or trackbacks (or on Twitter! - #uksg).
