I think it is plain and simply facebook and twitter which are killing RSS. Most normal people have heard about twitter and facebook and have no clue about the cryptic acronym RSS. Which, by-the-way requires a technical degree to understand, and to use (should it rather be v1 v2 or atom? does my pc support the best option?). Is it really a bookmark? Or an inbox? Or a notification? Now one should go through hidden features and install new apps. No sane person would set this up as opposed to a single click in a browser to a twitter feed or the push of a like button.

Like webmail displaced most "normal" people's imap/smtp (with all the firewall misery). Google groups/forums displaced NNTP.

I also feel sad, because RSS was free, while twitter and facebook are careless computing.
