I have seen quite a few tag excerpts that contain pointers to choose a more specific tag or only use if... but almost none that suggest it might be better to ask in a different Stack Exchange community. I asked this on Meta Exchange but it was suggested the correct answer was probably community specific.
I have specific instance in mind but I'm sure this applies across many tags here that are duplicates (in meaning if not always name) on ServerFault and other communities here on Stack Exchange.
I realise that every case will be individual but when a tag has much more traffic, even though it is pretty much on-topic in either community, is it correct etiquette to suggest in the tag wiki that the question might be answered quicker on ServerFault (or some other community)? Specifically this would be done to avoid possible migration and get the user an answer quicker.
I think such advice belongs in the wiki excerpt so to be immediate obvious but am interested in others opinions, as it would probably better suited to the main tag wiki which is not just plain text.
The situation that inspired me into this thought was a Question I had regarding denyhosts - before I made it I did consider whether it belonged on ServerFault or here on U&L, I chose here based on the fact
denyhosts is pretty much a *nix only tool, it does work on OSX (which for the most part I consider unix) and probably could be made to do something sane anywhere Python exists but... also the fact that many use it outside of server type environments, to protect themselves when on less trustworthy networks.
Anyway to cut a long story short, the question has got almost no attention and I have been doing quite a bit more background research, some of this has made me aware that denyhosts doesn't get that much use here but has a little more on SF, and also it is regularly misused in both places. I contemplated asking for a migration but thought it was worth being a bit more patient and in the meantime thinking actually giving some content to the tag wiki in both places may help with the misuse issue. This led to me thinking that maybe one tag wiki excerpt should actually suggest it might be better posting in the other community if the question was more on topic there... and here I am still pondering that fact.
