html link rev?

["bryan" <bry@itnisk.com>]

Anyone have an idea of what percentage of User-Agents support  link rev=”prev”  and link rev=”next” ?

Also on the prevalence of said User-Agents and as to what type of technology they are, i.e search engines, aggregators, browsers etc.

 

I’m wondering if it’s worthwhile to take a particular solution for linear document collections and add this to them. Any experience with this?
