I have been using the free version of Commun.it and I love it. I am about to sign up for the paid version when another site I am using expires. Commun.it helps me schedule my twitter post and handle all actions on my twitter account. It tells me all the people twitter posts that have mentioned me so I can thank them, shows me the top tweets so I can retweet them, shows my followers so I can decide it I want to thank them, follow them back, see who is not following me back, see who to consider to unfollow, gives me leads of people to follow, top tweets to share, and lets me schedule posts. I love this site!
