"Start to ambitious" does not parse as English and adding "#1" does not help; "addon" is also not a verb, and if we substitute "add on", the phrase "add on to Google faster" still does not mean anything.
Is this petty? I don’t know. It bothers me to have a completely inscrutable title on the home page.
Edit After looking at the page, it would seem this is, indeed, an incredibly lazy submission title: It gets its name from PG’s essay on ambitious start-ups; replacing Google is ambitious idea #1, and apparently building Yahoo! Axis on Google counts as insanely ambitious. "Addon to Google faster" is supposed to convey "extension (?) for faster Googling."
On the linked page, you will find the odd choice of Myriad — Apple’s constant ad-copy font — and Jobsian phrasing (“insanely great”). Apple has nothing to do with this. Then you’ll note the poorly-chosen phrase “searching Google” — no, you’re searching the Internet with Google. Results are not limited to Google.
I suppose one could say I am being cruel, but there are maybe 20 words here and most of them are erroneous or poorly chosen. I don’t think it’s “just” a language barrier; PG’s essay was in English, and yet even the phrase lifted from there managed to corrupt all the words!
