This is super offtopic, but it thought it was awesome: on the ActionBar in the PushBullet android app, the pullout drawer icon makes it look like the bullet (your logo) is being shot across the screen (like "action lines").
Good for Google upping the limit here. Similarly when I developed a search engine using Google's API I too exceeded the query limit on the first day; however, At a rate of $5/1,000 queries with a daily cap at 10,000 I was forced to redevelop using the Bing API.
Yeah, what's amazing is that they didn't charge us to increase the limit. It's also pretty awesome that their android push notification service has no quota and is free.
I'm impressed that the quota was lifted so readily. I've hit quota limit issues with other Google API services and hit brick walls regarding raising them.
In the recent past, even with a premier paid account on GAE, getting a specific quota raised took a few days and was apparently a non-trivial operation.
Using GCM for Chrome is free but you do have to have an API key (unlike some Google services). The 10,000 messages cap is is what they call a courtesy limit, hinting that you can get it increased, but we had never gone through the process of requesting one, nor did we feel we were necessarily guaranteed an increase.
(Adding a credit card didn't let us increase the cap.)
It made me smile :)
