    Our cogroup entry is described here as 'meager'. Can we expand it?

    Sure we can. We just copy the good parts of the MO replies over to it.

    That's the general idea: discuss stuff elsewhere and archive the stable and useful bits here.

    There is the issue of unattributed copying that Ben Webster brought up. Perhaps we could encourage MO to enforce a policy whereby unless otherwise stated any material is deemed open to copying into nLab - a little like the approach to organ donation which relies on opt out.

    So: attribute it.

    Copy it here and in the references say: "this is taken in parts from the discussion at http://..etcpp".

    We do this elsewhere. For instance at multisymplectic geometry.

    I mean, I keep saying "copy and paste" in order to emphasize how little effort it is.

    But of course, please, there might still be the possibility that somebody reads the discussion there, understands it, and then reproduces his understanding in his own words here.

    Given that I was one of the contributors to that discussion on MO, that there was nothing said there that I didn't already know, and that I didn't cut-and-paste anything at all, I don't particularly feel the need to attribute anything. I suppose it might be thought useful to have a link to that discussion, but only in a general sense of regarding n-lab and MO as symbiotic rather than competitive so wherever there is a topic in both it may be useful to cross-link - but then this should be done on a more systematic (and automatic) basis.

    Anyway, I've made a start and I've renamed it cogroup object. For the time being, co-H-object also redirects there.

    Obvious things to do: generalise to monoidal categories, add in links, think up more examples.

    Thanks Andrew!

    Now if only the MO link to cogroup would correctly redirect to your new cogroup object. Is that the redirect cache bug at work that Toby keeps mentioning?

    Yup, that's the cache bug. At least, deleting the cache copy made it work. Now all I need to do is get enough rep on MO to edit that post and remove the word "meagre". I need another 650ish points for that so someone needs to get over there and start asking questions on Tall-Wraith monoids and Frolicher spaces!

    lol

    But seriously, it's good that the "meager"-comment is there, except maybe one should have given a better reaction to it than I did. But it is important to make people understand that of course there are lots of things missing on the nab, but that this should make them want to put them in, not complain about it.

    Yes, I guess the ideal result would have been for the querent to rewrite the n-lab entry based on the answers that they'd received.

    Exactly. We should promise them "reputation points" if they do so.

    It would be funny if we could make contributions to the nLab eligible for "reputation points" (whatever those are!) over at MO.

    PS: I'm NOT suggesting "reputation points" for the nLab, but for those at MO who care about such things, it might make them more willing to contribute to the nLab.

    I might just be an interesting psychological experiment to see what happens when we create a page reputation points here where we list names of MO contributors with a number behind them, which increases when they show up here.

    (Not being serious, hope that's clear.)
