SO I PUT UP THE POST ABOUT AIRPORT DELAYS and a minute later my cellphone rang. It was Hallerin Hill, who’s teaching a class in communications for the MBA program at UT. He wanted to know how I was blogging from the airport — I explained it was via the Sprint wireless card. Works great, even where there’s no wi-fi.

UPDATE: Hallerin texts that it’s the UT “Executive Development Program,” not the MBA program. See how fast we can fix errors in the blogosphere!
