Good relevant suggestions, nice twitter/Facebook integration. Very helpful to any blogger
comes up with the right suggestions whenever you need it. friendly and smart thing.
best social plug-in i ever used.
Installed headup on a tip from a friend. Used it for research on an academic paper I'm doing on Investigative Psychology. It found for me sources that a search on Google scholar didn't. I'm sold.
One of the nicest thing was when I hovered above a blog or news post (Like ReadWriteWeb or CNN) - Very interesting data was fetched...
a very clever idea! headup gives a fresh and easy way to get around the net. i can't wait till it goes out of beta!
It's fascinating to see what's out there on the internet using headup. It's much easier for me to reach all that information out there.
I got to see stuff I didn't know where to find, or didn't even know existed. Here and there you may find some minor problems, but overall - fantastic.
I'm fascinated by the simplicity in which this add on innovates the whole web experience and changes the focus and relationship between the web and me
Headup is the next thing on the internet!
It allows me to be lazy, and do all the work for me!
Have a very nice look & fell to.
I was first skeptic when first heard about headup but it seems it all works juts fine. Nice design too.
very cute and useful tool. at first i didn't know what to expect, but headup really delivers more than I thought it would. I especially like the connectivity with last.fm- it actually lets you stream music and see the lyrics with one click.
very pleasant interface.
Waiting for a while for a good mac version and finally got it.
The data I get is surprising every time. Lots of fun.
headup is great! - I installed it while it was still in private Beta (got an invite on Mashable... ; ) The coolest features are the social aspects you get after personalizing the addon. Things like seeing which of your friends love the same music you do, who you know in which company or city and what friends you share with each of your contacts. Works great as a boost for google as well.
The only thing that takes some getting used to is the hover pop-up.
