iWise - Wisdom on Demand
An interesting new web service has just come out - iWise was described by its CEO Edo Segal as twitter for the dead... ominous tag line? yes - ominous service? definately not.
iWise positions itself as "Wisdom on demand". With an fun and interesting home page, Albert Einstein theme, and a massive repository of quotations from famous people (whether incredible minds, actors, philosophers, you get the idea) organized in a twitter-esque style. You follow famous personalities and are "revealed" nuggets of wisdom at arbitrary times.
iWise recognizes its similarity to twitter, and lets you register through your twitter credentials and has extensive twitter integration, which definitely make the service worth taking for a spin.
