Application Search Database
Being unable to install software is a common problem cited when it comes to average Joe using GNU/Linux. But, I think, the harder part is just figuring out the name of the program you need to do a task.
You're Joe User, and you're new to Linux. You finally figure an e-mail client out and your Aunt sends you pictures of the family, including your ex-gf. Well, you know you want to just color right over that _____. So, now what? What program edits images? Wouldn't it be nice if you could search somewhere: "I want to edit an image."
So, the thought is, a website which contains a database of Linux compatible applications (mostly Free I imagine) that you can search. It'd only need to go over keywords really and it'd tell you what applications do it, allow users to post comments about the applications, and tell you how to install it on several distributions. Even if the application is not in the distribution, it could at least tell you how to install it via source (from several distributions).
It should probably also let you filter your results by your distribution, and actually help you figure out what distribution you're running. Often this can be done with just the user agent string, but there's always some heuristic way to get at it from the users standpoint, they just don't know them.
What do you guys think? Does it too closely re-replicate what you can already do on apt frontends? I know apt has a NASTY tendency to give faaar too many search results. We could narrow things down quite a ways, obviously by discluding libraries.
It could also be a useful center for geeks who just don't know which applications are the best for something new they're trying.
