I think that a good social media app is something that free up your time so you can spend those in engaging with your audience, and not just scheduling posts. There’s this beta site featured at Oneforty.com called ‘Garious’ and I’ve been using that for three weeks now. Wow! I don’t have to think of the exact time and date those updates will get posted. I can even grab my favorite RSS and link it there. The tool will automatically post it on both your twitter and facebook accounts, randomly, as if posting like a real human would. It took me like 10 minutes to schedule a week’s worth of posts that normally takes 1-2 hours. Well, that’s what I use.
