Cocoalicious is a neat open source app for posting links to a del.icio.us account, and browsing through your del.icio.us library (pun intended) outside of your browser.
Sadly, for some users recently, Cocoalicious has been broken. For some reason it simply wouldn’t connect properly to del.icio.us accounts. Old links were stored just fine, but new ones couldn’t be added. At least, that’s how the problem manifested itself to me.
Anyway, the good news is that there appears to be a work-around. Take a look at the very final comment on this blog post and you’ll find simple instructions for amending the Keychain item for your account in Cocoalicious - doing this seems to get things working once again.
