I didn't downvote (can't actually), but some possible reasons are:

* No one is interested in the GP's bookmark list.
The author appears to be a female sysadmin, in Ireland, with some time in Google, or a contractor for Google.
Really excellent stuff, and you know, sorry for my irrelevant comment, but something, any comment can serve to get a deserved link up onto the front page.
