I can thoroughly recommend Twitter even if you don't want to tweet. If you're on your laptop (or whatever) anyway, worth logging onto it to follow any event (like a cricket test match, say).
Through a slight oversight in the holiday booking arrangements, I was forced to follow the General Election results coming in, from our apartment in Santorini. Following it on Twitter was really good. I was already following many of the political commentators, but I'm sure if I didn't know who to follow, then the #GE2015 hashtag would have sufficed. As it was, I was treated to a nice mix of news, commentary and humour, all in chunks of 140 characters. Most memorable, apart from the discussion about Ashdown eating his hat, was "Has @rustyrockets (Russell Brand) conceded yet?".
