Before I used Instapaper I had a 30+ tabs opened in Opera. And I was used to that, though whoever saw it was asking me how I work in Opera with this amount of tabs. :) But to get the content into Kindle to be able to comfortably read it I started using Instapaper. Sadly in recent version of Opera the “Read Later” bookmarklet stopped working (yes, it’s reported to Opera). Not good, I’m pushing through it a lot of articles into Instapaper or Kindle respectively.
At the beginning there are two variables to put your username and password. The code does what fits my needs best. Opens new tab issuing request to Instapaper and closing current one (because I’ll read it later 8-)). Raw return code is processed with my brain, no fancy popups or anything like that.
201 means OK; everything else means “check Instapaper”.
Improvements are welcome.
