I like pinterest a lot. I have observed that I got followers in pinterest faster than facebook. Although I got more followers in twitter than pinterest, I still find pinterest as more interesting because of the images. People post various kinds of genre from nature to clothing to food to funny conversations. I love it. One thing that I love with twitter though is that you get to schedule your tweets ahead of time.
I don't think the people here get what you asked.
Well, the only social media tool I've been using now (probably my favorite) is buffer app.
It enables me to scheduled my posts, and let me filter my search, when searching something on twitter.
