Yes ... and no.
I'm still emailing my blog list with beery messages. In fact, there's a backlog of twenty or so waiting to be polished up. When they're done I'll be moving over to this Twitter malarkey thingummy – fortunately fumbly illiteracy is allowed there so I won't have to do any editing.
What I won't be doing is calling posts "Tweets" as the word reminds me of "the Tweets" who were responsible for a minor crime against humanity – the execrable "Birdie Song".
[BTW "The Birdie Song" is still popular in the tents at Oktoberfest 28 yrs after it was an international hit.]
