Do you need a mobile-optimized version of every websites you read on HN?

I read many articles of blogs every day and 98% of them haven't a mobile optimized version of their website. So I need to carefully zoom in and move left-to-right to able to read the post.

Building an optimized version for mobile of a website (blogs, newspaper..) is expensive because require knowledge of HTML5, best practices of JS, CSS and it need to be compatible also for older mobile phone.

So i think how to solve this problem. Build an web application that grab content of a external website (via FEED RSS or scraping) and show it in a optimized version for mobile. Each website that wants to have an mobile version of its blog need just to put a link to this website. Example: www.mobileversion.com/?site=http://nytimes.com and it start to see a mobile version of that website, created by web application, without really need a mobile version. Just inserting a web link. Do you think that could be useful?
