I dunno - a blog post reporting a news story isn't really any different, to me, than a news website reporting a news story. In this particular instance, Cory is supposedly reporting on a story in the news - it's not an opinion piece, or an editorial. It's straight up reporting, no different from the reporting in the Guardian. Call it a "post title" if you want, but it serves the exact same purpose as a headline in a newspaper - grab the reader's attention. And when it's a misleading headline, it serves to alienate a certain subset of your readership. And that's fine - that's an editorial decision that Cory has chosen to make time and time again, and he's free to do so (as I mentioned above)... But when one is reporting on the actual news, even if one is not a reporter, I find it distasteful when one deliberately mis-reports it in order to generate more outrage (and thus, web traffic). It should be outrageous enough that a senator is implying it (though, I'm not sure the senator actually is, as per my above post), there's no need to ramp up the outrage even more.
I'm aware the BoingBoing is a blog, and not a news site, but I like to think that they're generally much higher quality than shitty linkbait sites like BuzzFeed or HuffPo, and Cory's fairly consistent mis-representing of stories in headlines (even if he then actually goes on to report accurately on the story itself, as he mostly did in this piece - my disagreements about the actual implied allegations notwithstanding) tends to drag the site down somewhat.
But I digress (quite verbosely) - back to the subject at hand, I'm still not convinced that Obama is being accused of anything by the good senator in question. I went in and read the original letter, and it feels like a big stretch to say that the senator was subtly implying that the President had ongoing knowledge of the spying in question. Considering that the report about said spying came out on Wednesday, and the senator's letter was sent on Tuesday, it doesn't sound all that crazy to me that the senator was referring to the CIA Inspector General’s Office pending actions on Wednesday. Again - I would not even be remotely surprised to find out that Obama DID know about it as it was ongoing, but it seems like the evidence here is pretty thin, indeed.
