remember analog radios where you twisted the dial to tune in/overshoot/turn back to a signal? remember how gratifying it was to get a clear channel for a while before you tucked behind a hill? that is what the 'social web' feels like right now...
every few months we hit a new strand/clear channel and the fidelity is great for a little bit, and then we overshoot/undershoot and have to hunt for a clear channel again.
why? because the medium is the message.... and the mediums keep changing.
1. for a while in late 2008 i feel like i was tuned in on twitter with high velocity of relatively high value communication... there was a lot of margin in the format and the lines were clear. since then, twitter while still great, has felt a lot more noisy/jammed.
2. facebook has felt the same through several cycles of fidelity and loss, but that is because unlike twitter, they have an 'auto-tune' function in the form of news-feed. you aren't turning the dial, they are.
