I downloaded and installed Google Drive right away of course.
I can share a folder publicly, which is useful.
You can also link to an individual file in Drive.
This link should take you to a picture of the White House if it's working. Only sort of. It tkes you to a page that includes the picture. I'd like to link to just the picture. Let's see if this link lasts. :-)
The picture of Carlos Boozer to the right was being served from the Public folder of my Google Drive folder, but then the link broke. So you can't point directly to a file. The link isn't persistent. That's an advantage that Dropbox has. Here's the link to the small picture of Carlos Boozer on Dropbox. It won't break.
Drive begins with the same two letters as Dropbox. So when you're typing the name of one into the browser's address bar you'll see the name of the other, if you've been to their website.
Question -- will Google's search engine go into folders that are marked public. I don't see why it shouldn't. I think they want to go in there.
Gotta wonder how long before Google-Plus features show up when you view a folder or a file.
