Why: Tech public relations folks and journalists have a love-hate relationship. Brooke, who runs Brew PR, knows more about tech than most people, and she won't bombard your DMs, inbox, and replies with pitches, either.
Why: Tristan, an early Foursquare employee, is still relatively new to the venture space. He tweets a lot of inspirational stuff about business and tech in Silicon Valley, and he's got a super positive attitude.
