Bloggoggle, good but ...
Came across Bloggoggle from Steve Rubel's blog. Seems to be nice service but why have they made signing-in this difficult?
Compare this with what we have in Zoho Writer or Zoho Planner.
Reminds me of a recent Seth Godin's post on using 'illegible' capchas (it was ticketmaster.com that got Seth pissed off)
