I actually stopped using Pocket (phone/tablet) and just use Send to Kindle for everything. It doesn't bother me too much that I can't archive/mark as read articles, I just delete them from my kindle once I'm done. Also I just order the articles by most recent and just use search if I need to find a specific article. I wanted to avoid relying on hacks so I guess this setup will be stable for a while.
It's actually amusing that since back then I've used ipod touch, android phone, android tablet, and now the kindle, for specifically reading articles from the web.
When I was in college I was actually printing web articles in batch during weekends, I just paste the plain text to MS word arranged in 3 columns in uniform font so it looks like a newspaper. Those were fun times since everything was so new to me :) that's way before all the instapaper/pocket came out.
