Probably a firefox extension or chrome plugin, but also a web directory where visitors can install greasemonkey scripts that will add keyboard shortcut functionality to various apps. The full add-on will be promoted to be able to notify you of configuration change possibilities and specific website productivity tips, all based on the current URL in view. Users will be able to change/add/remove keyboard shortcuts for every URL.

Challenges:
- compatibility
- change monitoring
- conflict resolution

Ever since I installed MobileScrobbler on my iPhone, I’ve been using Last.fm a lot … like almost every day, and for hours at a time. Here’s my profile. Last.fm “scrobbles” (keeps track of what you listen to, and uploads that info) your music, and my iPhone automatically does this when I listen to anything in the iPod feature, and so does my Mac when I listen to anything in iTunes. Why do I want to do this? For posterity, as you might imagine, but Last.fm also provides music recommendations in the form of a personalized radio station. And the personalized radio station is what I really love. I mean, you press play, and you’ve got all sorts of new stuff to listen to, and the percentage of it that I like is much higher than listening to anything else. And it’s more interactive, because I can teach the system my preferences by pressing either the “Love” or “Ban” buttons.

Anyway, MobileScrobbler lets me read lyrics while I listen to songs… Which I LOVE doing. That Mac version however, does -not- do this. I was able however, to find a Greasemonkey script that adds lyrics to the song page on Last.fm, and therefore enables a workaround. (Greasemonkey is a FireFox plugin that I use daily… it let’s you add things to, and modify websites. People make scripts to make all sorts of websites do all sorts of cool things. Check out http://userscripts.org for examples).

My workaround is this: Listen in the Last.fm app. When I want to read lyrics for the current song, just click the link in the app to open up the song page at last.fm. The greasemonkey script shows the lyrics right there for me. Works.

Oh, and then I can also comment on the song right there too, another feature I’d like to see added to the Last.fm Mac client.

I’ve started a new blog… http://techgetscrazy.blogspot.com

I’ve decided to make Rex.FM more of a personal blog, while I’ll post my crazy, tech-related posts over at TechGetsCrazy. I feel like it will be a better outlet for my ideas without pushing my personal brand too much. I mean, I really want Rex.FM to be about me, not my crazy ideas. So anyway, expect some coolness over there, if you’re interested, and subscribe via Google Reader or whatever if you like… feel free to expect some awesomeness. http://techgetscrazy.blogspot.com

I’ve been looking for a way to blog from my iPhone, especially because I wasn’t having much luck with the WP-mail plugin that allows you to post by email.

Anyway, I’m writing right now on my iPhone using a plugin called WPhone, which you can find here: http://wphoneplugin.org

You can now expect a lot more posts from me here!

I just saw a post by Robert Scoble, where he mentions the iPhone interface for Facebook that Joe Hewitt created. Facebook for iPhone looks pretty slick, I’ll admit that. But it is also missing a ton of essential features.My top wishlist / feature requests:

• Commenting on photos
• Edit Profile info
• Message people from their profile
• Groups

These are all things that don’t work on the current iPhone interface, but seem like a serious missing feature. Now, I’m not sure who to point my finger at, but I’m disappointed that there’s been no apparent improvement to the iPhone interface since it was released about 6 months ago.
