I confess it: I'm a sucker for analogical thought. So taking the idea of a blogroll - even if I don't actually use the things - and coming up with a "searchroll" - a personalised list of sites across which you can carry out searches - is intrinsically appealing. This is what Rollyo has done: I know it's not exactly new, but the last time I looked there wasn't much to see. Now there is.
For example, I was rather taken with this Russian library searchroll, which somehow makes the idea nicely concrete. I can see that you might well want to search through a group of related sites, rather than wade through several million Google hits.
The only problem, of course, is that you either have to set up the searchrolls yourself, or try to find one that suits your needs. Fortunately Rollyo has done the obvious, and come up with a search engine for search rolls. From here you can enter keywords and try to piggy-back off someone else's collection (all in the spirit of sharing, of course).
I was impressed with the range of open source searchrolls that are already available. Open access searchrolls are thinner on the ground, while open content is waiting for its first example. Any offers?
