It appears that public posts are not really viewable by everyone of the web; when I click on a post URL when I’m not logged in to Diaspora, I get the “join Diaspora” screen instead. Is it a bug or a feature? IMHO, it severely limits the usability of Diaspora as a social network.

Correction: found out that public posts are viewable on the user’s page and on tag search, but not by URL because there seems to be no permalinks because post IDs are different on every pod. Still, a huge problem…
