I do this every month. I don't call it a 'give-away'. I call it 'rent'.

Yeah, my ex-girlfriend told me that in *her* house, the ditch is one way... You must have known her too.

Given that it's something that is designed to be installed on any domain at all, it may not be required to be called Diaspora. I don't know many people who refer to their gchat account as jabber.

Not quite right. The square of the number of nodes takes into account all possible subgroups among those nodes. Reed's Law takes this number and removes singletons as well as the empty subgroup. You link to Metcalfe's Law, which does only deal with pairwise groupings and follows a pattern of triangular numbers (i.e., for five people there are ten possible pairings). Someone who is more adept with the mathematics than me should be in charge of actually saying which of these is more suitable for representing the value of social media websites, but it seems that Reed's Law is what you're looking for.

It already is.

Emacs?

The learning curve for Lilypond is really no worse than for any other text-based music typesetting software -- and far easier than, say, the TeX music packages. ABC is a little more simple on the surface, but is so much less flexible as to make it useless for complicated music. MusicXML seems to be a good transport format, but as parent points out, it's clunky: like any other XML format, everything is perfectly readable and will take a year and a day to type.

Lilypond, which seems to me to be the best option for open-source notation software, is probably not a worthwhile system for creating on-the-fly snippets for web pages. Something JavaScript based would be nice for that, and it seems likely that there could be wiki plugins that could be used to create musical examples without huge dependencies (much less specific versions of any given large software packages), or a knowledge of how to use these large, complicated notation software packages. There might still be the problem of being limited to simple examples, but do we really need all of Lilypond and its dependencies to create an example of a Phrygian scale?

...wait, they'll give handj-- I mean, I can go to Starbucks on these asteroids? Sign me up!

Is it bad that I've remapped the Caps Lock key to send rm -rf?

...that's one way to get a Canon to work with Linux. Perhaps the only way, for most of Canon's printer models.

Though it may not be quite as easy to read initially, a prefix or postfix notated expression would work well on a (probably wrapped) line, and could therefore be good for simple text editors (which is what I use for taking notes). People experienced with this (LISPers?) would be better suited than I am to say if this would work well.
