I thought this could be a very helpful thread.
Sometimes a video is worth a thousand pictures, and a picture is worth...well you get the idea.
I'll start:
Orchid Web Youtube Channel
These videos are produced by Orchids Limited, a nursery in the US. Lots of videos on individual plants with growing tips. A great way to find that next plant to buy!
Brad's Greenhouse
This guy has a beautiful setup and hundreds of fascinating plants. A real inspiration, as well as lots of instructional videos, from how to grow an oncidium to how a pitcher plant digests its victims!
Please post any more links to videos/channels that might be of interest to orchid hobbyists new and veteran alike!
