Coinbase just upped their price to match Mt. Gox. Do they know something we don't?
This is a very recent development -- as of late this morning their price was still approximately matching Bitstamp.
Edit: Well that didn't last long. Hit refresh after posting and they're back to matching Bitstamp again.
My guess is that it won't go lower than $420

413 and dropping

My guess is that it won't go lower than $90.

Ah, no. I'd say we're maybe 25% of the way into "Awareness Phase". Institutional investors are just getting started. The current rally, however it ultimately turns out, is naught but a tiny blip on that chart. Figure "first sell off" maybe this time next year, then the real growth kicks off.
Meanwhile Bitstamp is heading back up, at least for the moment...
On the positive side, this has to finally be the effective end of Gox as market leader. Who wouldn't pull out of there after this?
$600 going... going...
Maybe then people will stop using this childish 'HODLING' word after they get a good SPANKING
I think you meant to say SPNAKING.
But the one thing I can't figure out is what caused the dip (see below) this last summer. I believe a lot of people (myself included) think we will see something like this play out again. But does anyone have a rational explanation for why this might have happened in the first place? I remember this moment well: everyone on local bitcoins in Vancouver was sold out of coins (or asking ridiculous premiums) which I thought was odd (it was as though it was clear to everyone that the price was too low).

Actually, there's no mystery about what caused that dip -- Gox officially suspended withdrawals on June 20th. The market began dropping immediately on the news as people speculated that Gox was going under. The price bottomed out at 66, bounced back at about the same rate it had fallen, then resumed the pre-news trend of meandering around 100 before ultimately heading upward and into the November rally.
FUD aside, the really interesting question is this: Is the current price normalization on Gox permanent, or will the Gox price quickly rise back above the other exchanges in a week or two when Gox resumes BTC withdrawals but still can't process fiat withdrawals?
Damn, that's a big red candle..
It is, but I feel like I've seen this particular episode of the Bitcoin Show so many times now that it's not even worrisome.
