Moblogs may just be one good indicatr of current effort and future performance. I'm wondering what else might provide insight:
* Webcams of parking lots * Traffic surveying indicatrs for regional effort (not that I want Silicon Valley traffic to return to where it was) * RFID that CEO * Indicatrdriving -- Using Wardriving tools, especially catching exposed images over wifi with Etherpeg
It's going to get easier to aggregate across tagging domains. Lets toss out some ideas and commonly tag them as indicatr here and in del.icio.us.
With enough weak signals, you get a strong signal.
