The Gillmor Gang spent a rare Sunday session raking Twitter over the coals. Well, some of the Gang, that is. Scoble and Marks chimed in from Austin, while the others stayed behind in SIlicon Valley. But the split divided differently over Twitter’s move to lock down client development. Marks and Taschek thought Twitter’s move was heavy-handed and a mistake, while Scoble agreed with me that Twitter was in the driver’s seat.
