Angela Godwin at Water World does a great job. She goes to the major conferences like WEFTEC and ACE in addition to doing a regular video segment for their website. In fact here are a couple of interviews of a couple of my colleagues:
My boss, Cindy Wallis-Lage, being interviewed at the recent ACE conference this year...
James Barnard being interviewed about the beginnings of BNR...
http://www.wef.org/Modeling201/ oh wait, it seems you have to be a WEF member now to view it. Ah well. OK so here are some other WEF videos, mostly of things from the annual conference WEFTEC but there are some other interesting videos too:
LIFT program (along with WEF), focused on Mango Materials. It feels like a vlog even if it isn't one!
So, there are some pretty neat videos out there but no a whole lot of poop-focused vlogs, per se. So maybe there is room for the Poop Engineer to try moving pictures!
