I was about to search for a taskwarrior tutorial on YouTube but first I think of search on asciinema.org. I was very disappointed when I realized there is no search tool on home. And AFAIK nowhere in the site. The closest thing is in /explore/public. I didn’t found if this was already mentioned:
I think asciinema.org could be the YouTube of terminal screencast, there is a huge potential, adding some of the great features YT have like rate, view count and playback speed control (very important since typing is slower than reading).
Even could be a comment area (more pro with ratings like reddit) and (why not?) a nerd social network.
