I am trying to post an answer on TeX.SE and am stuck at:
The dots continue and I never see the captcha. For some reason,
meta.TeX.SE does not have a concern with me being human.
Also, why is there not an exception for this once you reach a certain rep cap? It seems that this is needed only for really really new users. Have encountered this a few times in the past and find it quite annoying.
I like procrastinating as much as the loyal TeX.SE users, but this is getting in the way!! :-)
