Over april and into may so far, iStock seems to have been enjoying a slight resurgence for me.  Nowhere near it's former glory, but at least making up a little ground.  Very welcomed, indeed.  Anyone else seeing something similar?

Comparing the first two weeks of the month (day 1 to 14)...

From Mar to April I was down about 20% on IS.

From April to May I am up about 10% on IS.

These are typical changes for these months, so from looking at my data, I'd say things are normal... no resurgence, no crashing.

Not for me.
Jan - March were up on the same months last year for $$, and dls.
April was just under last year's for $$, way below for dls.
May is about the same as half last May, but only because I've had an EL but had none last May. Dls so far have fallen sharply compared to last May.
0 dls today; 1 refund. 

I'd say it has stabilised at the (much) lower level to which it has descended. That may be what gave Istock's management the confidence to increase prices yet again __ so it may not last for long.

For the last 6 days, except for Sat, I've been getting tons of sales, yesterday was my BDE without ELs day and it was Sunday! Today's sales are great, I'm mostly getting S sales today, But I got lots of L+ yesterday. Better best match placements for indies (I suspect, I rarely check it) and the fact that they've only upped the XS and S prices for exclusives makes sales at IS really good. I'm seeing the effects of the latter today, I didn't notice any change before (getting more small sized DLs as usually)
