Neat idea but it is way too animated, and the animation is too slow, making it feel inaccurate when mousing from one item to another. Somehow I also got it to bounce back and forth between two tooltips really fast by mousing from one bolded text to another.

This has potential but it needs a little less bling and a little more polish.

I like the idea too! However I also got the tooltips to flicker: mousing a few pixels above the bolded text.

Oh, I see. Yes, I should check the tooltip. Anyway, you can use your own style and edit the css file if you want less animation or something like that.

Looks cool, but it sometimes takes a while to show up and flickers Consider fetching Wikipedia data at page load. I set the window to fullscreen, hover over Apple, move the mouse over the yellow tooltip, and move it up a little bit until it it slightly above the tooltip's top border.

It's a lot better than the one in FastestFox, though. That one is horrible.

Quite similar to Google's official 'Dictionary' extension -- which I highly recommend: https://chrome.google.com/webstore/detail/google-dictionary-...

Good stuff! It'd be nice if the data was pre-loaded in some way that doesn't hinder the page load time. Not sure how, off-hand, but know it's possible.

Each link is a request to Wikipedia, so I thought it would be better to request only if the user mouse over and wants to fetch the data. But yes, could be an option to pre-load :)

I haven't looked at the code yet, but how modular is the data source? Incorporating things like Google's dictionary extension could make this a pretty versatile little tool.

I gave preloading a shot. Should work fine for you.

This is sharp, I like it, but just FYI: the tip never goes away on iPad.

it's just god damn slow.
