Yep, right now the extension is required. We're talking about future plans for people who like some of our features, but not everything — we want to be as unobtrusive as possible.

Our primary goal is to enable people to keep and collaborate content easier than before. In addition to discussions, we have a full-text search engine that incorporates into Google results, showing links you've kept if they're relevant to your search. From that standpoint, we're a "much better bookmarking platform". Over time, we'll be helping people discover interesting content, too.

This email-a-page feature is actually just our newest, and isn't the core of the product. However, it looks like many people really like this, stand alone. I'll bring this up with product, and see if we can come to something that will meet your needs. In a perfect world, would you like a more minimalistic extension that JUST did this, a bookmarklet, or something else? We want to be the easiest way to share and collaborate about content with others.
