So here is the count at the beginning. Try to reach at least 10k.
A good tactic would be to write a good profile text, add a nice picture and a domain I would like to push with interesting content.
All this in place will make it more likely that the visitors of my twitter account will follow me and if the website has good content come back also there.
Combined with more social tactics, SEO and other traffic funnels this can create a continuesly stream of traffic.
Perhaps I will add that later. As I've no real plan, no clear account/website purpose/direction.
You can of course copy an account you like.
For the beginning I'll make a free account at unfollowers.com tofollow and unfollow people.
The free account allows only 50/100, but combined with other websites/services it should create agood volume.
You can follow and grow your own Twitter account.
