I found the whole 'conversation' quite painful to read ... I cannot see any situation where a folder is more versatile than a tag or label, other than the fact that to emulate folders with labels you may need to do some 'unlabeling' when you want to move an item to have a new unique label. I haven't used Better Gmail 2, but it looks like it does 'folders for labels' (among other neat things), which could be useful. Will check it out next time I restart FF. - Andrew Perry

It could be interesting to be able to create sub-groups of social contacts withing friendfeed to be able to look at discussions from different groups separately. The same way maybe an option to tune out some feeds of other people. So far it is still possible to follow the conversations but I can imagine that subscribing to more people's feeds will be increasingly difficult. - Pedro Beltrao
