I do, I love the internet. I'm not obsessive about it, and I don't "live" here, as some are want, (in fact I don't "get" MySpace at all), but on balance I think it is ace. For those of us engaged in research the internet is an invaluable tool. I'm just a lowly PhD student, and so don't remember the dark days before Pubmed and the like, but quite how lit searches were done then, I have no idea.
Now, in these post-YouTube days, it was inevitable that JOVE, the Journal of Visualized Experiments, was created as:
an online journal publishing visualized (video-based) biological research studies.
Brilliant! So now (well, in a while, once there has been time for techniques to be submitted and uploaded), when you needs to learn a new techniques, and no one in your institute knows how to do it, you can watch a video of it, then have a go. Obviously this is no substitute for hands of tutoring in a experiment, but it is a great tool for those having a go on their own. Cool.
