Matt Smith | Matt Smith Won't Join Twitter | Contactmusic »The 'Doctor Who' star is always urged by fans to join the micro-blogging site - on which his co-stars Karen Gillan and Arthur Darvill are members - but after trying it out he has decided he doesn't want to tweet his thoughts and actions. He said: ''I joined for a day, when I was in Comic-Con (in San Diego), and it's just not my cup of tea. I spend enough time on my phone and I figure who cares what I'm doing? You've got Moff (Steven Moffat) and Karen and Arthur on there. There's a big 'Who' contingent, maybe I'll sort of dip in and out. I just don't see it happening any time soon''...
