   Format: MarkdownItexI don't know. But I regularly get "502 Bad Gateway" errors when opening and saving $n$Lab pages. Consistently so when asking for [https://ncatlab.org/nlab/show/n-stack](https://ncatlab.org/nlab/show/n-stack).

   Format: MarkdownItexI think that you\'re referring to the address that I use for the nlab-talk Google group. I mean to respond to that! The quick answer is that, yes, there are a lot of constructivists that eschew formalism, including Brouwer and Bishop, but they're not the ones coming to constructivism via category theory or mathematical logic.

   Format: MarkdownItexThanks! It seems to me such a corrective to Carl's comment might be called for; not sure. (To all: I'm referring to a comments made by Carl Mummert at MathOverflow [here](http://mathoverflow.net/questions/228697/constructive-compactness-for-countable-models#comment564974_228697), saying roughly that constructive mathematicians tend to shun formalization. Something about that didn't sound completely accurate to me, so I emailed Toby for his opinion. Again, sorry for the off-topic interjection.)

   Format: MarkdownItexRead in isolation, the comment does sound wrong, but since it was a response to a comment about Bishop's constructive math it makes some more sense. On the other hand, I think the people who call the latter "BISH" do generally tend to have a particular axiomatization in mind. And to be honest, I feel like the constructive mathematicians who shun formalization are a dying breed, although my experiences are of course biased.
