Faceache I can't get really get into, although I do have a page.
Twitter has worked out well for updates at the TT (police bulletins, roads closed, race news),
and also for warnings of possible Aurora Borealis!
Bearing in mind I have an £8 phone from Asda, not one of these 'smart' phones, I have to activate Twitter to send texts from the relevant people.
I've learned after the first year,
when I got Twittering texts from all and sundry, ran into 100's of texts over just 1 race, and me battery went flat!
