I'm not a lawyer, but unless the publisher agree, you're probably not fine. IIRC, Instapaper and readability run on the client. They don't reproduce the complete article on the server.

I'd also argue that you're in a morally murky area. Call me old-fashioned (and give me one while you're at it), but I respect these journalists and the people that pay them.

What about the Amazons "Send to Kindle" service?

I think I am a dead man now.

I'll try to understand the legal issue.

I will also try to find some journalists and start learning how to respect their job.

Thanks for reminding me.
