You can certainly use the form that way, as your own instance of a checklist, and it seems the site has the purpose of providing such mini 'applications' in a local-store friendly manner - see the Travel checklist on the same site, for example.

3-digit slashdot ID's notwithstanding, I hope we see a revival of cute little cottage-/hobby sites like this, or a kind of perpetually simple cache of folks who just render their genius to static files, in cute ways, and leave it at that... over and over for a few years.

No, but you could keep checking in on them and seeing how you're doing on a semi recurring basis.

I agree with this. This is more of a list of reminders to keep in mind IMO.
