I am a huge fan of this team and their tool. We already use it and it has caught a bunch of issues before they became bigger problems.

We've already had those "wow I'm glad we have this tool" moments, just a couple of months in.

Yeah they must. I wrote one once too to power this: https://extstats.appspot.com

I wrote it to track our competitors (I used to work at HubSpot) but you can add any other extension in the drop down on the left.

What happened to it?

Also, how do you deal with duplicately named extensions?

Incredible to see how many of the top extensions in terms of growth are spam / spyware extensions (ask.com for example). I'm sure it's a game of whack-a-mole for the admins of the Chrome Web Store.

Distribution deals, I am guessing. If you bundle your chrome extension with an installer (Ask Jeeves, when you install Java or Adobe) it's a lot easier to get distribution.

I assume the larger the number of reviews, the higher the engagement of users with the plugin (if they don't think it's part of the browser).

I had the same thought. Awesome.

I like how the options are already pre-filled for you. It took me a second to realize I should scroll down, I wasn't sure what to do (if some element was clickable, etc).

good point. issue was that it was hard to fit the description and buttons above the fold. something clickable to scroll would have definitely been a good idea.

I think that Facebook has been so successful because it appeals to stalkerish nature in everyone. They want to browse the site, see what people are doing, and what is going on in their lives. That's why I think it's more powerful than what LinkedIn is doing.

I think people are more interested in changes in their personal life (or friends lives) on a weekly basis than careers on LinkedIn. I agree that LinkedIn is focused on business and someone's career, but I think that there is far more potential in doing the same thing but on a personal level (which handling it carefully, as you suggest).

I think that a heat map of friends is a good idea, but it's a one time element that is useful for you and potentially your friends. I'm thinking that the newsfeed aggregator would be better at getting users to come back into the site on a more frequent basis. Maybe it isn't needed as much because so many of Facebook's users come back to the site on a daily basis.

Interesting feedback! Thanks for the comment.

I'm sure that's right. There are more eyeballs doing searches on Google, and there is an auction between advertisers pay to put their ads in front of users. More advertisers chasing users probably gives them more revenue per search.

Shouldn't there be some sort of parity?

A user is a user is a user. Unless google users are that much more likely to buy something after clicking my ad, why would you pay more per individual view? Sure the absolute numbers should go up with more views, but it doesn't seem like money well spent to pay more for similar adspace.

That would assume that people using Adwords compare costs with the other ad networks before deciding to advertise. I would guess this is most often not the case.

Actually, for some industries, Google traffic converts much better than Bing/Yahoo traffic. No 2 traffic sources are exactly alike.

For years Yahoo! converted 30% better than AdWords on the same keywords for several of my active CPC clients.
