I hate to contradict you, but I think it IS actually Bloglines...

I've had the same issue with them with a number of blogs, even my own where I KNEW I did not update past posts, but Bloglines was got confused and thought I did...( http://coolthingoftheday.blogspot.com/2007/07/bloglines-issues-posts-being-marked-as.html )

The only way I've found to deal with this is to edit each problem feed and turn off the "Mark As New if Updated" option.

It's a pain, but seems to usually work.

But then there are times when Bloglines kinds of freaks out and thinks all my feeds/posts are "new"... I had 30,000+ unread posts one day a few weeks ago ... sigh...

Bloglines is had this issue "old posts are new again" issue for other people too, and every time Bloglines seems to say it's not them.

I dig Bloglines, been with them for years and they are getting better, but sometimes I just want to... to... well... yeah.

Anyway, take care and Happy New Year,
Greg

I used to have the same problems with bloglines as well with another feed i used to read. Every day two posts would always come back as new with every one new post. Since switching to google reader that feed never has given me that problem. Very odd but I'm glad somebody else has noticed.

Try www.google.com/reader. In a year of use, no problems reading Scoble (or at least, no problems that were Reader related).

Wait, you asked bloglines, a corporation who's profitability relies on people using their product, and when they denied the problem was with their product, you believed them? :)

I concur with the "it's bloglines" theme. I use Attensa as my feed reader in Outlook and never have duplicates from either of Robert's blogs.

Ditto here with no issues using google reader.

Another ditto, there's nothing wrong with Scobles feed, I get no dupes.

A tip for next time you question where the problem comes from: Go find the original rss feed, look at the raw xml and see whether Robert, or any other blogger, have dates that seem to be changing in their feeds. If they haven't changed the dates, your RSS reader is the one to blame.

I had similar problems with NetNewsWire, but Google Reader, as others have said, never has problems on this level.

Not Scobles. I assure you. I've blown off bloglines because they cannot help but suck.

Thanks everyone for the feedback. I have been very happy with Bloglines over the years; its only been in the last month that Robert's feed has borked.

I'll open another support case with them and see what comes of it.

Hello Dana,

I believe we have fixed the issue for now on the Bloglines side. I have posted a reply to Scoble, with more details at:

Feel free to email me if you have any questions or continue to see issues.

Thanks,
Paul

Thanks Paul!!!

Thanks Paul. Turns out the issue was actually a bug on Wordpress.com's side. Matt Mullenweg admitted to that and said he's fixing the problem: http://scobleizer.com/2007/12/27/bloglines-sucks-2/#comment-1811745
