A bit of background: I have Asperger's syndrome. One consequence of that is, generally, even a simple half-a-page post takes from 30 to 60 minutes to write and leaves me quite tired. (Which, as far as I'm aware, is much slower than average.) On the other hand, sometimes I get in the mood, feel all giddy inside and enter a sort of word-mincing berserker rage, in which case the words seem to flow a bit better and faster and less tiringly.
Also, due to various life-related reasons, at the moment I have about 4 hours of free time I can spend with computer.
So, for this reason, I have created a list of topics I would like to ask (and been wanting for quite some time) on various sites of Stack Exchange, and been carrying it around for two weeks until I finally got into a mood where I can write at a reasonable pace and had enough time.
Perceived cause: 40-minute limit per question seems to be applied across all sites of Stack Exchange, even on unrelated sub-sites (possibly applicable only to the stackexchange.com domain).
The problem: I posted a question on Sci-Fi StackExchange. Then I tried to post another question on Sci-Fi, but ran into the 40-minutes blockade. That's perfectly reasonable and understandable - a common mechanism to stop the site from being flooded with spam.
So, I switched to Gaming SE, wrote a question from the list... and was greeted by the same message. Even though the last question I posted there was 20th February. I checked back to the question on Sci-Fi SE and, sure enough, its timestamp said it was posted 33 minutes ago.
The actual question: Is that a bug, or is that a feature? If the latter, what's the justification for it?
If that's intended, does this mean that instead of writing questions and posting them once I finished, do I have to save them to a text file, and then post them throughout the day with an egg-timer in hand?
EDIT: Posting here, on Meta SE, did not re-trigger the limit, and I managed to post a question on Gaming SE, but when I tried to post a question to Sci-Fi SE, I got the "You can only post once every 40 minutes." again - 1 hour after the original question on Sci-Fi SE.
