Yeah-hoooooo!
The actual implementation of Firedoodle stinks. The idea, though, rocks my world. You can draw on any web page. When you come back later, your drawing is still there. I deleted it moments after installing it because the drawing tools are lousy and slow and bleah.
Then there's MyStickies. Same deal, but with text-based sticky notes instead of drawing. Lower technical requirements result in better implementation. The verdict: MyStickies is good enough for now, I've installed it and I'm keeping it.
The future: a hybrid of both that actually works. With easy sharing. And a social ranking system for other people's notes and comments. And customization of the social ranking so I can say "always show me comments by the following people." Organized into layers, maybe. Like Google Earth. Let me see public commentary. Let me see my friend's comments. Let me see editorial comments. Whatever.
And why only have comments on pages where the comments are enabled by the administrator? That also means that the admin can modify and delete comments at will. A third-party comment manager will be more fair and ubiquitous. Why should I only see Amazon reviews that Amazon allowed to remain on the site? Why not have a comment thread on every single web page in the world?
Whee! I dunno. This is one of those things that just totally fires my cool engines.
And then the future future: marked up reality.
We can't markup reality, yet. Physical reality. But the web is a great playground for technology that might migrate to physical reality someday. That will be soooo cool when it does.
Cell phones with GPS -- one big step in that direction. Man, I want a phone with real GPS access. Not like Sprint's lousy restricted system. I want to have GPS-triggered alerts, with a web-based backend for management.
