Prediction for next 10 years:

Clear virtua-glasses (computer screen glasses) you'll wear hooked up to read RFID tags implanted in people or implanted in other people's virtua-glasses....when you walk by peers (especially at college), a futuristic version of their "facebook page" will appear, you can save it for later or read it right then.....

stalkerish-yes, weird....eh, I think Facebook was "weird" at first....of course, it wouldn't be stalkerish, you'd be able to tweak the privacy settings, allowing for only people in your network to view your profile.

just an idea...
