I checked out Ma.gnolia today. First the good: groups and private bookmarks are nice and the UI is clean and simple. But, there is some bad, enough of which to keep me away for now. A few things really bug me:
1) The domain name is terrible (as mentioned previously).
3) Build a firefox extension. Bookmarklets are ok, but an extension with quick access to adding, viewing, viewing popular, viewing tags, etc. makes it much easier to use a social bookmarking site.
So, it’s back to delicious for now, but if they keep at it, I’ll try it again later on.
I emailed them this same feedback and I got a response back from Todd Sieling, the product manager. Sounds like the domain name is here to stay. But, they may be open to changing the re-direct urls into something a little less obtrusive. Todd also reports that an API is on the way which may spur more tools/extensions.
