BTW, when Twitter supports 10K messages, think about using it to transport JSON structures. It's high availability and performance these days, and their identity system is solid. They have something and I imagine Jack knows this. I met with him once many years ago, before all the turmoil, and he said he wanted Twitter to carry arbitrary payloads. With this limit gone, we will be able to do that.
Nice idea! So tweets could transport a lot of machine-readable data. Ideal for loose-coupling of webservices? Even hashed/encrypted messages could transport private info.
Besides data, what if I write Markdown in a 10k tweet en there would be custom twitterclients that could render it properly?
