[Updated: 12/29/10 at 11:23 AM] Thanks to all that emailed me — this looks to be a widespread problem for more than just my site. If you are seeing this please feel free to continue to report it and also report it to the developer of the apps that you are using. Thanks.
[Updated: 12/29/10 at 11:27 AM] Marco Arment the developer of Instapaper emailed to say that he is working on the problem. Please don’t flood his email box anymore. Thanks for your help.
To all readers using Instapaper for iOS could you please do me a favor and try to add this post to Instapaper by whatever means you usually do this. Once you do this can you sync your Instapaper account to your iOS device and let me know if the article shows up.
I have been getting scattered reports that an article (not linked list items) are showing as “unavailable” in Instapaper for iOS. This of course annoys me to no end and must be incredibly frustrating for you — the reader.
Shoot me an email to email@example.com and let me know if it works for you or not and the steps you took.
Instapaper appears to work just fine for the linked list items.
