As autumn approaches and the dawn chorus starts at a time more closely associated with my normal waking up time, I am still waiting to hear of litigation involving a tweet. 

Tweets may seem inconsequential but they could easily be disclosable. The scenario is obvious. A is involved in a deal with B and as part of the communication chain they exchange not only e-mails and texts but tweets. Litigation ensues and the tweets are deemed to be disclosable. 

Unlikely? Maybe, but impossible? I don’t think so.

[I am indebted to LegalSparrow for pointing out that the phenomenon of 'twitigation' is already upon us, see his/her comment here]
