I like standups. They keep me updated on what's happening in the code base, and give us the opportunity to discuss what's going to happen next. The repo is vast and we're gown adults that don't need to be micro-managed because story A or B is taking too long.
The problem doesn't come from standups, but rather from dysfunctional startup culture.
I have a similar experience. Standups keep me at least vaguely informed on what other people are doing, provide an opportunity to take the pressure off poor souls buried under a new influx of tasks, and are perhaps some light team building (such as the canned joke that a burndown chart isn't supposed to look even remotely like that, or something in the lines of "help me, those goddamn morons from $OVERSEAS_BRANCH at it again"). 10 minutes tops, and back to work.
If I were to compile a list of workspace annoyances, even the most pointless standup would be way after serious business like "people standing behind my back while talking to someone".
