Google Knol is a quite fine service but the randomness of the integration of knols into findable search items by the search function on the site should be explained and corrected.
My knol on microblogs still can’t be found, nontheless it’s published and publicly consultable at http://knol.google.com/k/pieter-jansegers/microblogs/1m1bmti438m47/2# .
Many other ‘knollers’ are experiencing the same problems and are talking about them on the help pages of Knol and the net in general.
