Internet Fishing
Fishing on the internet is quite fun the web is huge. Think of the web as a ocean, not a lake, but an ocean. Just imagine all the fish you can catch on the web to increase your RSS subscriber and there is several ways of doing it, but what is the good bait? That is what you have to figure out I think every one comes up with there own techniques sooner or later, but try to find something that will just increase that rss feed to where you can get them into your website and lock them in like there in a dungeon.
Think of something creative, don’t overstep the boundaries by any means by doing something silly, or unethical, but think of something that you can throw out there where they get hooked and you rill them in. You can use severals sites as your small oceans such as Digg, Reddit, Forums, and many other social driven communities, and you can even use PPC and search engines as another small ocean to catch fish. Give it some thought :).
