The way I see it, there are several fundamental problems with Ma.gnolia. Well, actually only one: they’re reinventing the wheel. I enjoy del.icio.us. It has a community of 30,000+ users. Sure, Ma.gnolia’s website looks nice, and it has some cool features, but it’s still not convincing me to switch.
And another thing, it’s URL scheme is rather daft. Why do they need that dot after the ‘a’? Is it just more ipping off of del.icio.us?
