Gubb

Gubb – it start appear in my google reader recently, it seem like quite a number of blogger actually blog about it, including Web Worker Daily

• It allow you to create different list , each list can be either Task or Bulleted
• You can send the list to your self or contact by email or SMS
• You can receive items from email or SMS to add on your list
• you can move the items from list A to list B ( someone choose this service because of this reason)
• there are a few pre defined font size and layout for you to choose

I would say this will be good List Management but not task management, there are no API and no export features ( ical, xml, rss all missing ), which i think Gubb might need to improve on these.
