At first I thought it was my clipboard. Then I thought it was my browser. Now I know there's something going on in the SEDE editor...
Hi, I'm Sam, and I sometimes string together long comma separated lists of user IDs and plug them into our data explorer to identify user engagement patterns and try to figure out how we can tweak features to make SE more awesome than it already is.
But I've noticed that I can't paste more than about 2300 7-digit IDs (and commas) into SEDE at once. I can however link sequences of 2300 IDs into SEDE, so we're not looking at a hard character count limit here. This seems to be an issue with pasting.
I'm told there are certain members of the community who maintain SEDE. Maybe you're out there listening? Any chance we can up the character paste count?
