Is this dangerous..?

Also bear in mind you will have about 100 psi in the tyre this is also trying to blow the rim out, safety first

nah, fuck it

avoiding the potential for a wheel to fail and get crushed by a bus is not worth the cost of a new wheel,

your suggestion is madness

It'll be fine. If it goes bang, it goes bang. You skid to a stop or fall off.

I say take the risk.

you can get new front teeth pretty cheaply in eastern europe these days i hear
so don't worry about your rim falling apart

consistancy is the forums forte

It runs along the seam of the rim, but the seem is turning into a crack at the top of the clinch.

Is this a "stop riding it now the shit is dangerous" kind of crack...?
Or can I get away with it until payday when I can afford a new rear wheel set up...?

It depends...

Just found and bought a rim gauge on ebay, less than £6 inc. postage. Looks identical to the one referred to above.

8 more available...

Make that 7, thanks for this.

Circled it to be clear.
Mad potatoskills on display.

It is a vertical split, one side definately sits higher than the other.

Whatever the specific verdict is, looks like I'm in the market for a new rear rim/wheel.

That rim is fucked.

I quite happily ride on a couple of broken spokes .. but a fucked rim and I am getting the bus.

Conti fail...
