If you think they'd make a good community FAQ or guide, I'd be happy to add them to our list (it doesn't sound like that's the case here, but I wanted to mention that, for others who discover this thread to).
Otherwise, r-bloggers and r-weekly are probably the best places to post stuff like that. We're intentionally trying not to crowd out all the great R community blog aggregators that already exist.
If you think this work might translate well into a podcast (audio interview), webinar (short chat and maybe visual walkthrough of your work), or office hours type community-event, we should talk more.
