Just received an email from instapaper, that their premium service is now free for everyone.
The following email:
"We're thrilled to announce that, as of today, we're opening up Instapaper Premium for all of our users, free of charge.
As a current user of the free Instapaper, this means you'll now have access to:
Full-text search for all articles
Unlimited speed reading
"Send to Kindle" via bookmarklet and mobile apps
Kindle Digests of up to 50 articles
An ad-free Instapaper website
Before, some of our greatest features were limited to Instapaper Premium subscribers. Now that we're better resourced, we're able to offer everyone the best version of Instapaper. You'll continue to have an ad-free Instapaper app experience, and we're eliminating ads on the web entirely".
Also, for existing premium users, the instapaper team will offer prorated refunds for your current subscription and you'll no longer be billed for instapaper premium.
