this is exactly the starting point for the project that evolved into credo (8 yrs ago)..

the WoT, (or as I termed it credibility graph in the app), can be a powerful mechanism for a whole host of applications, but this basic idea was the first one

but you need a viable graph before this becomes useful, and the problem with a stand-alone resume-focussed app is that people don't change jobs that often, so they don't feel the network

linked in didn's start out as a job platform either, nor could it survive without the social-marketing uses

one of the other problems is that the current social WoT isn't actually as useful for skills matching, it's not precise enough to score skills on, more of a 'who you know' thing

key idea of credo was to allow ratings of people/content by topic of expertise/interest, and use those to compute graph scores.

we're close to releasing a reboot of credo on nostr, should be fun to try it out
