Should there be a periodical (i.e. once/twice a month) effort to merge together various publishings of the same hack? I think it's important to do that, so that we don't have five differently-named but almost identical versions of a hack floating around after a few people add features. A list of contributers to a hack/library can be kept as commented "meta-data" within the file, and the hack can then be renamed to anarki.hackname.release.
Just like Linus Torvalds decided he wanted to be the Linux integrator, someone will emerge who wants to put together the best version of various variations of various hacks. If he or she does a good job, he or she will become respected and people will look first to him or her to find a version of a hack they want to use.
Information about a hack, like "this hack is the best of the bunch", is really best not put into the hack name, because later if the information changes (maybe you find out the hack has a bug), now you have a name that's giving bad information.
