Blogging cannot force the blogger to do anything.
It's his editorial decision to write about current affairs or not.

He changed his decision, that's all.

Current events are overestimated anyway. You do usually not get a good picture of events until months later. Many "breaking stories" are simply a waste of time, for their content is wrong or misleading due to insufficient time for research and analysis.


I also disagree on the atrophy of long form skill due to short blogging in general.
It may have happened to him, but do we seriously lose long form writing skills by writing in short form? Think of letters, e-mails, press releases, forum texts, blog comments - do all this short form writing hurt your long form writing skill? I don't think so. The opposite may even be the case; you train yourself to get to the point.
The only thing that suffers is the comprehensiveness of long form writing. You may train yourself to get to the point in long articles without casting light on an issue from ten different angles.
