How do I gain Twitter followers?

Create your own background image. However, do not make the image too much like an ad or sales pitch. The background image must be less than 800k and we recommend a size of 1600x1200 for a large image or smaller if you plan on tiling the image or just having it on the left-hand side. Finally, keep in mind that smaller resolutions and monitor sizes will hide much of the background.Change your profile picture. Use a picture of yourself to make it seem more personalized if this is your personal Twitter account.

Great service that sends an e-mail any time someone unsubscribes from your Twitter profile and mentions a possible Twitter post you made that may have caused them to leave. Fantastic site for managing your followers and getting an easy to read overview of people not following you back, quiet users, and inactive users.
