of course, a blog post like that is basically just worth sharing if the icons are free (which seems to be the case as I skimmed it). If I remember correctly these free icon pages were more colorful ones than described on css-tricks.com

shouldn't they have a backup site where it will automatically redirect if its down... but I guess a 301 redirect wouldn't work because "if its down its down".

just linking it to a github page where no other info is on there about it isn't helpful .
