The RSS notification service Blogarithm, first covered here about a month ago, has added a search engine to help users find feeds. It seems to be a fairly simple tool, in which search operators and even moderately complex keyword strings bring the results down to zero. A search for riaa brought in one result, in which the string of characters was in the site title; in other words, Blogarithm did not recognize the acronym and apparently did not search entry bodies. Such a basic engine might be productively replaced by a hand-built blog directory. But no matter; I am continuing to enjoy and find useful the daily delivery of RSS updates via email that Blogarithm offers.
