It's FollowFriday or FF in Twitter so a lot of people would follow you back, especially the ones who were on TeamFollowBack or something like that name or group on Twitter... I follow back, might as well add me up, ID is meiyah... thanks!
Do a search for your niche. Say your Twitter account os for your dog grooming business. Do a search for dog grooming. You will find a bunch of accounts that focus on it that have many followers. Then follow them. Many will follow you back.
I'm looking for a good linux app to do the scheduling of my tweets. I seen #followfriday but haven't tried it yet. using hash in your tweets help too eg: #Linux #joomla #Web #hosting #porn whoops They help for the search . Make another account to experiment too
You should try HootSuite, it works on Linux (web based). I believe it's the best twitter client and it's very powerful (can schedule tweets and lots of other things)
