Twitter Inc appointed Keith Coleman, founder of startup Yes Inc, as head of its product team, the third executive to lead the division in less than a year.
The micro-blogging service said it has acquired Yes, the maker of apps such as Frenzy and WYD-What you doing, which allows users to connect with their friends. Financial terms of the deal were not disclosed.
"Yes! Keith and team are joining Twitter to help lead and strengthen our service!," Twitter CEO Jack Dorsey tweeted on Thursday.
