Kyle over at Warpspire has an interesting post reflecting upon the impact that releasing a WP blog template (which got picked up as one of the templates offered on WordPress.com) has had upon his blog’s success of late.
The results include increased traffic, loads of inbound links (which helps with SE traffic, ranking on Technorati and increased participation on his blog via comments).
This shows the power of developing a useful tool that is useful for others but that will also promote you.
