Even after the world's most brilliant stick figures tried to make the case?
Well, you may already know this, but just in case not, here's another reason I just happened across. After a brief moment of terror, I mean.
It turns out, though, that Picasa did not delete everything I'd ever uploaded. Blogger is merely reflecting the new Google policy:
Picasa Web Albums and Google+
You get more free storage: Google+ provides free storage for your photos, which are automatically resized to 2048 pixels. Like Picasa Web, video uploads 15 minutes or shorter are free.
Actually, if you follow the quoted link and scroll to the bottom, you'll see that you don't actually have to join G+ to get unlimited image storage. (With the minor annoyance that, at some point, you'll have to resize your images to the 2048 pixel limit yourself, before uploading, rather than having Picasa do it for you on the fly.)
Anyway, a good bit of news, I thought.
(Now, will Picasa yet allow you to upload animated GIFs?)
