Well, in your user's opinions, it's an annoying popup. Half of us thought its recurrence was a bug, the other half thought it was spammy. I don't think most people are seeing the part of the text where it says that this is some sort of new feature. Evernote works well enough most places I use it, so if there was something I wanted to clip, I'd just try clipping it. I never ask myself "has evernote been optimized to clip this particular site?". By all means, keep optimizing stuff - making things "just work" is what makes a product great to use. But maybe don't interrupt us every time you do it
