Notes, video summaries, etc. are always welcome, I think. It would be great if in addition to raw notes, you add 1-2 sentence summaries to each note cluster.
Thanks for the response. I'm struggling with the content length limitations (2000 characters) and the formatting (no images, bullets, etc).
I also happen to be building a wiki / collaborative self-education tool that I'm using to take and then share these notes, but I don't want to violate etiquette by sharing these links if the perception is that it's primarily self-promotional. It is, but it's also value-promotional, I hope. Would it be bad form to do so?
My take is: If the karma.fm link that you're posting provides value to the crowd than it's not bad form. This will also enable you to get feedback about your site (design, accessibility, etc.) from the HN crowd.
Another (I think better) approach that a lot of people use is to post a blog entry (you do have a company blog, right? If not, start one asap!) with some learning/summaries/etc. that you think would be useful with links to the karme.fm pages.
The worst that can happen is: you post and get no upvotes. In this case try 2-3 more times being mindful of the post time (there are many posts on HN about ideal post timing, use https://hn.algolia.com/ to search). If none succeeds, well, you conclude people don't see the value in your notes. Maybe time to rethink your value prop. Good luck!
