Apple CEO Tim Cook finally joined Twitter in September 2013, but while he only tweeted occasionally in his first year on the network, he's been much more active on the platform lately.

Aside from tweeting about Apple events, holidays, Apple products and social equality, Cook also actively favorites others' tweets. On Thursday, for example, Cook favorited a handful of tweets about Apple Pay becoming availble in the UK for the first time, which is good news for anyone using London's transportation systems.
