No, I spot it now. But I wonder how many people actually realize that you can search the web from within Facebook. It almost looks like a side-feature while I argue that it should be a central feature of Facebook.
Yeah, agree I did not verify but it wasn't an obvious feature and I think my argument is still valid -- Facebook could use search as its central strategy.
As far as HN homepage is concerned, I don't know ranking internals but I think it is probably timezone issue -- as of writing this comment, the submission has just 7 upvotes and is still on homepage.
And as a side note, how do you manage to get all your posts hitting to HN homepage?
