I found this collections of reactions to be a useful barometer.
I'd love to be able to filter only on reactions of people AFTER they have read a paper or two in their field, but I guess we'll have to wait a few days for that.
So far I'm yet to find a serious mathematician who actually found something of interest by reading the results (e.g. understand a new proof trick or approach to a problem). Does anyone have links to such positive ractions?
