And a close up as requested…
I opted for twitter.com/timbull instead of @TimBull on the cards. Primary reason is I don’t like “dumb” cards that say Email: tim.bull@binaryplex.com, Phone: xxx-xxxx etc. when it’s obvious what the fields are in general. I didn’t feel Twitter has quite the breadth of recognition that for some of my potential clients, @TimBull would standalone, whereas twitter.com/timbull provides just enough context without saying Twitter: @TimBull
