Rollyo now let you export a searchbox to your blog, I’ve placed one on my sidebar to search my blogroll.
At the moment when you click the drop down you only have a choice to search across my whole blogroll, if I have time I am considering also listing each blog separately…so you can search “all” or individually.
There is also a feature to add a search roll to your Firefox toolbar.
It would be great to import a batch of blogs into Rollyo via an OPML file, if possible…at the moment you can search my Bloglines account via Feedster (as it can search the OPML file).
