Oh! about Getting traffic try these things.
Getting traffic form Social Networking may seems hard to you, (maybe not hard)but if you use it properly you’ll be earning lots in the years to come. Just sign up for one or more of the programs below (all are free) these are sites I would personally recommend.
• StumbleUpon.com
• Digg.com
• Reddit.com
Next, update your profile on each site you’ve joined, including your URL and photo.
Then, the next time you post something of interest on your blog (or see something on a friend’s blog), you just submit your apps url or books or whatever you are selling on Kindle to the sites.
these Social Networking sites and many of them expect you to be an active participant. play with it and watch and see how your traffic grows.
Hope it helps you. Good luck
