you see people these getting caught up with computers over nothing like some people have facebook, twitter, instigram, hi5, .....etc. i mean seriously why?, specially instigram its just a photo uploading website, why not just stick with one like facebook it has everything im not saying thats necessarily a bad thing but it does waste much more time.
They all do a lil something different. I use FB to keep up with friends around the world and IG has cool photos from people I don't know..
To have successful Social Media Campaign you must involve in every bigger Social Media site, so you can't stick with one..
