If you see the Linked section on the right (not Related), there's been a whole host of requests along this vein.

@slhck Let me reward a good edit on my question/answer (I remembered seeing that, but it took a bit of time to find!)

Is there a policy for or against providing executables and other self hosted downloads?

Your particular example isn't a duplicate answer; while they may look similar, they behave differently. The question about actual duplicates still applies though.

I guess you could also request an option (on the user profile/tag subscription page) to send emails as non-Markdown plain text.

I wouldn't really consider it a bug as such, since everything is technically valid. It's really just those plain text email clients that want to make things that 'look like links' clickable. Perhaps others may have a differing opinion, or a SE team member will give an official word on this (you may have more success on the meta.stackoverflow.com site, which is the network wide meta - also, try giving a specific suggestion, such as adding the space).

This looks familiar... :P

Of course, assuming a common prefix, you can search for tags with wildcards: http://superuser.com/questions/tagged/micro*, http://superuser.com/questions/tagged/micro~. See this meta post for details. Apparently, this only works if the URL is entered manually; it's broken for the search box (and is a reported bug).

those with high rep is rather ambigious/subjective. At what point does someone get considered high rep? High enough to have the vote down privilege (125 rep)?

Either could refer to virtual printers too (e.g. PDF printers), but I think you are correct in the distinction that printing refers to the process (e.g. printing from a program, or otherwise printer-agnostic) whereas printer refers to the device (virtual or physical) to be printed to.
