Another idea: Quite often when I see a tool that isn't useful to me immediately, but might be in the future, I like to follow them on a social media channel like Twitter. This way I get reminded of the occasional update in the future, at a time when I might be in a position to use it. I think other developers would be the same. Might be an idea to make a quick Twitter profile to allow this kind of thing to occur. Currently, you would need to remember to check back on your web site each time, whereas with the above approach, you have the option of pushing reminder content to people who previously expressed a "keep an eye on this" level of interest. Of course, it does assume that you are wanting to keep the product around for a while, and continue developing it :) A mailing list (often presented under the guise of "Sign up for the Beta program, and keep up with future updates") is another way of achieving this.
