We’ve been getting complaints about seeing duplicate posts in some feedreaders (and I’ve seen this myself several times at Planet Ruby on Rails). We like our subscribers and don’t want to piss you off!
Does anyone know what causes this? We are using FeedBurner with Mephisto (approximately version 0.8) and producing Atom. The feed validates.
Our guess is that it has something to do with updating the posts, but we’re not sure. It may also happen when updating the permalink (which I encourage my co-authors not to do after publishing. Naughty naughty!) On Planet Ruby on Rails, there is sometimes a problem where one copy of the post goes to “www.railspikes.com” and one to “railspikes.com” and one to the FeedBurner post link (example).
We have id, published, updated and link tags to identify each entry:
1 2 3 4 5 |
<id>tag:railspikes.com,2008-04-25:1351</id> <published>2008-04-25T18:57:00Z</published> <updated>2008-04-25T18:57:12Z</updated> <link href="http://feeds.feedburner.com/~r/RailSpikes/~3/277795704/startup-school-2008-misc" rel="alternate" type="text/html" /> |
Any ideas? We’d like to fix this problem.
