See, I have titled this page as "Where to look for Twitter friends?" and not as Twitter Followers.
Followers come and go but friends remain with you loyally for ever.
So, don't go around looking for Twitter followers; it is a waste of time. Unless you reciprocate, you will quickly find out several followers to 'unfollow' you.
Ok, where and how to find friends for as followers to your Twitter profile?
Go to http://twittertroll.com/. It is a popular Twitter search engine that gives you results in real- time. Find Twitters based on their Tweets that interest you.
I searched for Tweets on Link Wheel and all I got was tweets on link and wheels and not on linkwheel. Linkwheel keyword produced nil results.
Hmmm... not impressive at all!
