This might already exist and if it does then please let me know. BUT I was struck about tweaks to Twitter that would perhaps work well – that people may actually appreciate.
It would be cool to curate the content of our tweets a little more closely. The easiest way to explain it would be a love-child between G+ circles and Pinterest boards. We all tweet about a wide variety of things – day to day bits & more niche interests. Sometimes we follow a friend who’s daily tweets about their day are of interest to us – but who might also tweet about golfing results – wasted tweets that we skim over as they are of no interest to us.
Similarly we may follow someone who tweets about a particular interest of ours – a sports journalist for example, who gives us up to date information on our team, but who’s tweets about their personal life we don’t care for. It’s a familiar problem – especially as very few people tweet about a single subject, Twitter is about having a personality.
