I was listening to a recent TWiT episode with the regular roundtable discussions 
and Robert Scoble mentioned how Twitter has become his RSS reader. No matter how you slice it, Twitter is a news source and real-time feed, but couldn’t be considered a RSS reader.
With any current reader, you are able to control subscriptions, read and unread marks, better sharing integration across networks and exploring and finding of other feeds through services like Toluu. Twitter is a force feed of data from anyone that passes a link along to you.
While you build your own community of people you wish to follow, actually parsing the content is another thing, mainly when you follow ~16k people like he does. This would be incomprehensible even in a feed reader to keep up with the sheer volume.
Twitter is about getting in and out of the stream. Taking a dip in the information flow. You only drown if you choose. RSS readers store the data for retrieval when you are ready and are sorted nicely into tags and groups. Twitter is not close to this with lists yet and has quite a way to go, as I have noted.
With such add-on tools as the Feedly extenson for Firefox, your RSS feeds turn into a newspaper, list or magazine covers with incredible amounts of sharing integration.
Twitter works in the reverse since people need to be present and watching the stream to catch what you send out. Not many are able to watch ~16k feeds and have the time to see each and every one. Now imagine them in real-time scrolling by. You would not be able to click to read links by the time a slew of others roled across.
I think he is right in that is is a great news source, that I use as well, and has immediate impact on trends and breaking stories. But for real commentary, RSS is here to stay.
P.S. yes I follow Robert and I think he follows me as well (if I go use the tools on EverythingTwitter to verify). But I still don’t expect him to see my content scroll by. So I tossed an @ symbol in the title instead. Get it? My content will scroll by quick, but a conversation marker can be seen across his Twitter client.
