Regarding the "Dear Cyclists" letter, whose writer is peeved by cylists riding on Alma Street:

Park Boulevard and Bryant Street are presented as viable alternate routes, but they don't go all the way to San Antonio Road.

Consider a cyclist heading north from San Antonio, going at least as far as Charleston. That means crossing Adobe Creek. Alma is the only road across, between El Camino and Middlefield, and might be the safest among those three.

OK, so why not then cross over to Park at Charleston, or cross over to Bryant at East Meadow? Personally I tend to do the latter. But many cyclists, just like many motorists, want to get where they are going as quickly and directly as possible. For roads shared by 2 or more travelers, we all know the right-of-way rules and signals.
