Zettels - another note taker, access via your mobile
SoonR - access your desktop from your phone
Watchr - create and follow topic buzz sites. If you search for a topic and it isn’t there you can create it - add tags, filters, related sites, related topics. This topic site will now list the latest sites, news and blog posts about that topic…tune the topic as you wish. Kind of reminds me of Boxxett.
