I take your point about the length of the webinars when put on YouTube.
Team e5 and eFixx do, as you say, have a massive wealth of knowledge between them, I can see thr comment about reigning it in a while (in terms of length) but they have always said from the outset that e5 stuff is just a bunch of mates shooting the ----, engaging in technical debate and just recording it. While they could benefit from shorter videos (or even chopping videos up (beyond time jump links in thr description - If they don't do that I'll put it to them), I don't think there's their style; SparkyNinja and John Ward tend to run shorter (20-45min) content on thier individual channels however.
eFixx on the other hand set out, from thr outset to build on thr shorter format that Gaz and Joe have used successfully in thier channels. I do (at times) feel they're just parading the latest and greatest kot/gadget/innovation and becoming an Electrical version of QVC; now if they did follow ups 6-12 months down the line, once thr financial incentives (if any) have lapsed, then I'd probably watch it more, as it is I only watch thrm now for the noncommercial (I.e show and tell of latest gadgets) content as that still harks back to thier pr-eFixx roots.
