The big legal publishers are increasingly involved in the world of social media (see blog posting about Twitter from earlier in the year).
I thought that it was worth flagging up that Lexis has a number of blogs which are worth a look.
For discussion of current legal issues in the news, I'd recommend looking at Halsbury's Law Exchange, whilst the Future of Law blog aims to highlight changes and identify trends in the ever-evolving legal profession.
For both of these blogs you can sign up to have alerts sent directly to your email inbox, set up RSS feeds, go to the relevant Facebook site, or of course follow on Twitter.
Lexis also publishes blogs in a number of practice areas, including family and IP&IT which will be of interest to those currently studying these areas.
