Even Google gets things wrong sometimes. (I don't mean like Buzz. That's more like "Even Google completely nukes a section of the internets and then attempts to apologize later, as if words could somehow make up for the incredibly stupid decisions they made.")
Have you nominated your area to be a test market for Google's reported 1 Bbps fiber service? You should. I did, and when I submitted the form, Google politely told me that while they'd saved my information on the page (good), there was something I had to correct ...
One of the boxes could contain no more than 384 characters.
Why 384? Who knows. (Typically it's 255; you may get smaller numbers if they do something to the text going in or coming out, and I suppose this could be a natural-language field, but I digress.) The point is that they showed me a restriction after I submitted the form ... and not only that, they didn't even tell me how much I had to change.
Ah, Google. Just like the rest of us, aren't you?
