Just a quick bit of info...
I recommend NOT doing the "Listen to some sentences and answer questions" HIT by NIDL Lab, as they have a 30 minute timer, with a 5 minute demographic section and a 30 minute "do as many as you can in 30 minutes" portion... meaning absolutely not enough time, by my 3rd grade math skills.
I did the entire HIT, hoping it wouldn't be that stupid.
Spoiler: It was. Time ran out. Contacted requester. Will inform if there is a reply.
(also, it was for $3, which is already not great for minimum 30 minutes...)
*sigh*
Poop.
