Gemara. Why does the mishna discuss this matter? Is blogging not permitted? Blogging is permitted unless one has sworn a vow not to blog. If one has sworn before witnesses or if one has sworn in a public writing. It is public if there are two witnesses or if one witness can supply a URL. And if the URL is a dead link? Then, it is appropriate to check the Google cache. But R. Yehudah taught: If there has been removal of a document from a URL, one may infer that there is no intention to swear the vow.
What is a day? R. Ashi said: From midnight to midnight. In the opinion of R. Ashi, it is required to use Greenwich mean time. But whose time stamp would R. Ashi use? Some say the time stamp at twitter.com. But the sages said: From 18 minutes before sundown to the coming out of [three] stars. R. Jose objected: A man sends a "tweet" 10 minutes after sundown. This counts for two days according to the sages, but it is only one "tweet." But how may one think of this? A "tweet" is connected to another before or after it. It counts as one, according to what it is connected to. The halakha is in accordance with the sages.
Why 12? A baraita teaches, one for each tribe. R. Shmuel said: One for each two hours. This cannot be correct. A day is more than 24 hours. There is no contradiction. An hour is one-twenty-fourth of a day according to the sages.

That was hilarious. R Jose and the others are old friends of mine. I encounter them every Passover at the seder.
