Go back and tell them this is unlikely to be the issue for your blog.
What they are referring to is the guid element that each item in a RSS(2) feed will contain. WordPress by default inserts the URI (permalink) for the post in this field.* In fact it is attached to each post as a record in the posts table under the column ‘guid’ (if that’s not clear enough). By any definition, a post’s permalink will be an unique identifier.
Looking at the source of your site’s RSS2 feed, I see exactly what I expect to, which is the unique permalink to each post in each guid element.
* Technically the guid can be defined as an url (the guid attribute for this is isPermaLink), though WordPress sets this to false. In any case, it has nothing to do for how a syndication reader interprets the ‘uniqueness’ of what is used in the field.
i am having the same problem. google reader shows some of my posts written in may this year 2 be written in last year.
i see in my feed at http://blog.ravidreams.net/feed/ that the guid is the post id not the permalink. i had previously imported posts when i moved server and that resulted in change in post ids and i had 2 delete a few. is it possible that some of the old post ids r used and that’s y they r shown as old posts? how to change this post id guid into the actual pretty permalink?
i am confused since igoogle, firefox live bookmarks can all update correctly and only bloglines, google reader having a problem. is this really not a blog feed problem?
Thanks
