Russ posts about a federated Twitter. Here's an unformed half-thought, partially drawing on our experience with measuring progress in Scrum: maybe it's better in some circumstances for something to be 100% down than 95% available.
Case in point, from the software development angle: it's easy for software, or parts of software, to be 95% done. For about 95% of a project. Getting something to that it's-nearly-there stage is easy, it's completing it (working out those "last few integration problems") that causes all the heartache and pain.
So it is with a messaging system. If 5% of my emails aren't getting delivered, I'm not in a 5% worse situation than 0% of my emails not getting delivered - it's *way* worse than that. Suddenly email is rubbish, because I have to consider that my email might not arrive.
Same with free software: 1p for a download is a radically different price to 0p, because I have to think about paying.
And ditto with a federated messaging service: I'd rather Twitter (which I love but have never paid a bean for) was totally dead, than kind-of-working (maybe delivering my updates to most of my readers, say... or giving me updates from some readers but not others).
Dave Wiener has been blogging about this recently, might be worth a look:
