I have never heard of this engine and Drudge is running a headline about them challenging Google? Needless to say, I entered all of my sites on their submit page, but damn I wonder how they got that link. I guess all it takes these days is to somehow squeeze "Google" into an article headline about your site and... bingo, your a player!
Some engines are interesting and notable because of the refinement in technology they're pursuing, rather than a market share type thing. Excerpt from the article:
Some of the search engine's artificial intelligence features include being able to search from acronyms, autoantonyms (words that can take two or more opposite meanings), eponyms (names from which other names are derived), hypernyms (a word that has a more general meaning than another), and hyponyms (a word with a more specific meaning than another).
Totally interesting and timely. At this point in time, it's cutting edge technology in the infant/toddler/childhood stages of development. AI utilizing those type of lexical factors is related to neural network technology (used by MSN Search).
It could be a real dark horse type of technology, and there's an increasing amount of attention being paid to it. There might just be big rewards in store for the first one to come close to perfecting it for use in mainstream or significant second-tier search.
Acquisitions of well developed technology by companies with very deep pockets isn't unheard of in this day and age. ;)
Note: Having interest in these type of things is generally restricted to geek-types, or those who have too much time on their hands - and even some oddball afficianados with a passion for search. Until it means $$ to be had, then it isn't egghead, ivory tower drivel any longer. ;)
