IMHO the icon for "favorite question" looks like a pentagram (Wikipedia). It doesn't really bother me but maybe other people :-)
Totally agree. May be we can use some ideas from this question (especially visa stamp) for the new 'favorites'-icon?
It is a pentagram. In so far as it's a five-pointed star, and a pentagram is also a five-pointed star. I used to draw them in the margins of my math notebook as a kid... My late grandfather had a six-foot one welded together from angle irons that he hung and lit at Christmas. Why a five-pointed star I asked? Because a six-pointed star would have meant we were Jewish, he replied.
But I digress... It's part of the whole "sketchy" theme that beta sites are stuck with on SE. It's supposed to look like someone drew it, on graph paper, like those idle doodles I used to do instead of learning maths.
When your site graduates, you get something else. 'Til then, don't be sayin' nothin' bad 'bout my grampa...
