now Can snowblossom channel be used for creating static website that don't use database?

there are some CMS for creatting static website:

https://jekyllrb.com/docs/ Jekyll is a simple, extendable, static site generator. You give it text written in your favorite markup language and it churns through layouts to create a static website. Throughout that process you can tweak how you want the site URLs to look, what data gets displayed in the layout, and more.

@r yes it can

Part of the goal is to make a platform that different people can use for whatever makes sense to them

so static web sites work really well, that should work fine now. Just create a channel and upload the files using the GUI
