I was working on writing a guest blog post today, and I was talking about a specific spinning video I have seen. I went to re-watch it to reference it, but it has disappeared from you tube. I notice this quite a bit. A lot of videos I have watched and loved have gone. I don’t know why, often they just look like old home videos so I don’t think it can be copyright? Sure I’m finding new videos all the time, but I miss the old ones. I consider the European style spinning with spindle and distaff a dying art so it is sad to see an old video gone.

Perhaps it would be wise to download onto a chip for safekeeping. I’ve had this happen as well – and I used to save them in an I Tunes folder so I could watch them on my iPod. Until they upgraded their system and my music AND videos started disappearing from my iPod. Now I just save them to a chip.
