I was told, in a jQuery/Python comment box project of mine, that I shouldn't worry about making it friendly for non-javascirpt browsers.

I think I still should, since some people use script blockers. A comment box should work even on a nokia brick.

On the other hand, I'm the only person in the world, in the past several years, that has gone to my site with a cell phone (not to be confused with smartphone).

So... What's your position on this? Do you fear this type of incompatibility when you're planning a web app?

Yes-ish. This isn't just people on Motorola Clamshells. It's an accessibility issue in general. (Think screen readers.)

The bread and butter of your site should work without Javascript. I can't think of a good justification to require Javascript to post comments. Some optional nifty stuff can be Javascript-only. Also, it's courteous to tell people when their Javascript is disabled that they are not seeing everything because of no Javascript.
