I understood the US States part. After that, you lost me.
FWIW, I’d like to be able to Search by dates. And I’d like to be able to go back to posts that I made 8, 10, 12 yrs ago just by doing a date search.
Search by date/date range should be an option.
Like most (all?) other forum/social media sites, we should have at least some time to fix our own errors, resulting in a "edited timedatestamp" note.
As noted up in suggestion #3, the Author would be fished out of the metatags etc, and would also wind up in the Tags system for simplifying finding by-same-author.
User-selectable sort options would be nice.
