Sometimes we're thrilled to see a follow from a friend, colleague, or person we admire. It's a joy to return the follow then -- but what if it's an anonymous person with an egg for a Twitter avatar and a string of spammy posts? We talk about who we will and won't follow and why, and hope that we're still on each other's lists at the end of it. What are your follow criteria? Comment here or on our Facebook page, or tweet us @RoundAboutChat.
