I offer up several feeds for my blog, one of the formats being Atom [1], a much nicer (and better specified) than RSS (Really Simple Syndication) [2] (which I also offer by the way). There exists an Atom feed aggregator [3] for Gemini [4]. The Atom specification [5] allows zero or more links to a blog entry. I discussed this with the author of CAPCOM (the Atom feed aggregator for Gemini) and it can deal with multiple links. I don't know about any other Atom aggregators out there, but I'm going to find out, because each entry now has three links per entry—one to the web version [6], one to the Gemini version [7] and one to the gopher version [8].
I have a feeling this is going to be fun, and by “fun,” I mean “it will probably break things somewhere because who is stupid enough to use more than one link?”
Of course, becuse of the way I translate links for the gopher version, those using gopher won't see the web version of the link. Sigh.
