Based on my experience, it isn’t. I’ve asked subscribers and they have the same problem. The Android version either captures nothing or the first one or two paragraphs, which is essentially useless. Try it with the latest Maureen Dowd op-ed.
The Instapaper website did the same thing, but now if you click on the text button of not able to be Android Instapaper’d NYT articles, it directs you to the article page rather than a clean ad-less Readability reformat. Android Instapaper has always done this for me, I’ve had it for about a year.
Instapaper, Pocket, Readability, Kindle – whatever save it later app I use, I usually save the article to Evernote as well, just in case I lose/lose control of my archive. With Evernote, I have the option to export them all to html so if Evernote goes out of business…
One drawback of Instapaper for Android is it doesn’t save a certain subset of NYTimes articles while the iOS version does which is enough to make you switch to Pocket or Readability or Kindle if you read the NYTimes a lot on an Android device. There’s no search function either.
