Torah on Twitter

On Monday, Rabbi Irwin Kula came to speak at our school and brought up the issue of tweeting Torah, suggesting that it will likely elicit in people one of two responses: either one of nauseousness or of opportunity (mine was the latter). (Granted, not many of my fellow YCTers are on Twitter, and, after passing around Rabbi Kula's tweet about it, there was some backlash against Twitter (not too different from this amusing video), although Twitter has not been a rabbi magnet [yet], so it's not confined to my school.) My first thought was that although there is some Torah on Twitter, most, if not all of it, is simply a providing of links to Torah elsewhere. For instance, @RabbiGreenberg tweets self-containted Torah Tweets, as well as, to some extent, @TorahTweets and @TorahToday. However, most of the Torah Twittering is not self-contained, such as @WebYeshiva, @YUTorah, @JewLearn, @JewishTweets, and @JewItYourself. While this is, to some degree, helpful, it is not confined to Twitter. For me, who gets a lot of tweets to my phone with URLs, if I'm actually interested in checking out the content of the referred link, I can forward that tweet to my email, where I can check it later (unless I am using my computer at that moment, then I can just open up the Twitter page and go from there (meta-comment: looking back in a few years, how outdated/obsolete will this aforementioned be?)). However, what I believe Rabbi Kula was suggesting was a challenge for more divrei Torah (or, what I'm thinking is more manageable, divrei halakhah) on Twitter, itself (without reference for external links). With divrei halakhah, for instance, a very manageable possibility is to do a daily devar halakhah, perhaps for people to stick with a given topic for awhile or to topically do more consistently.
Oh well, we'll see if this is taken up at all. (I held off the entire post about rabbis struggling to limit themselves time-wise, even to 140 seconds, let alone 140 characters, phew.)
