If you install Jetpack on your WordPress.ORG install and activate it and you provide Staff with both the .wordpress.com URL and the new URL for the WordPress.org install Staff can then transfer your existing subscribers.
How do I still gain wordpress.com blog followers?
The same way you did prior to the move and that's by commenting meaningfully on blogs with similar content.
Let me be clear in this WordPress.com and WordPress.or
g are sepearate. WordPress.org provides free software and peer support forums and that's it. When you move your content into a self hosted WordPress.org blog that blog is not part of the WordPress.com community. The posts do not appear here in the search in the Reader or anywhere.
