I just released Wordcycler 1.4. The only change is that Wordcycler will now fetch every page of multi-page articles, which has been a long-time user request.
If you're a frequent Instapaper user, you might ask why it has taken so long when Instapaper itself has been doing this for a while. The answer is that Wordcycler, since version 1.2, doesn't pull the article text from Instapaper.com; instead it pulls each articles from its original site and cleans it locally. I do that to avoid slamming Instapaper with hundreds of requests at once (you'd be surprised how many people maintain 400-item reading lists).
NReadability is maintained by Marek Stój, and powers his Instafetch app for Android and Windows Phone 7. I was extremely lucky to find NReadability - he posted it a mere days before Instapaper stepped up its rate limiting, which broke any Wordcycler version prior to 1.2. I plugged it in to my code was able to release a repaired version 1.2 almost immediately.
The one thing NReadability didn't do was fetch multipage articles, so porting that from readability.js was my side project for a few weeks in November. About a week ago, Marek accepted my patch and released version 22.214.171.124. I’m happy I was able to contribute back to this great project.
