It's pretty simple to use once you have some basic understanding of what each platform offers.
There are many different skillsets that can be used in this space - I'm currently using it as an engagement tool before applying my resume out into other platforms like LinkedIn/Angelist etc. Currently looking at more sales focused tools but still giving feedback here! We're solving recruitment problems by making our job search process simpler than ever through better matching people with jobs they love (by leveraging social media recommendations). I like that it provides an interface to find vetted experts in your field who are well worth working with or learning from rather than just scammers/cowards taking advantage of people's desperation over job losses due COVID19 pandemic! Not sure what else there would be as this has been very useful so far - we're looking at making our internal HR system more open via self service using these tools vs relying solely upon existing systems which don't have good integrations (or even integration!).
