Viability of *apps* on Gemini?

[tayevnge]

Hello,

Please help me understand viability of creating simple form-based apps
like message boards, job offer boards, etc on Gemini.

I am aware there are no multi-input forms but there seem to be an
"input" feature.

Does Gemini support or intends to support meaningful user input and
interactivity?

Is it realistic to build real world "text applications"?

How about multi-line user input, file upload etc?

Any example apps?

TIA!
