An update to the referencing posts feature:
Actually the timestamp URL could be used. The question is how do you reference other posts? I was thinking that you somehow use the unique ID of a post (e.g.
post:3041). But wouldn't that be too complicated? Why not just enter the link to another post and let the parsing of the content take care of the rest. But then again, the timestamp URL maybe not be the best solution. Because what if in the future your are able to move a post from your personal feed to another? The timestamp URL had no chance to stay linked with the new location. With the ID URL it would still work.
