From the Best Practices Search Engine Forums, aka "IHelpYou," the following threads caught my eye this week.
An author came in looking for advice on publishing his book online on "how to search," but the thread goes over a lot of different issues in self-publishing.
Doug Heil's entry into the search engine chart wars represents the most up to date chart currently online. Finally, someone has made a chart without copying Bruce Clay's mistakes - hopefully this will encourage others to check the facts and realize that Looksmart's secondary search is really powered by Wisenut (not Inktomi), that Overture's ads have been replaced by Lycos Insite in more than one place, etc.
Last but not least, a discussion of click-through rates on organic listings, in which the notion that "any top ten listing will do" is tried, convicted, and sent away for a long time.
