According to Google Operating System:
“If you sign out of Gmail, you’ll notice that the storage doesn’t
increase. It used to increase with about 0.33 MB a day, but the Gmail
team forgot to add the code that manages the quota increase after 31st
December 2006.
On April 1st 2005, Gmail space increased from 1
GB to 2 GB and started to grow every day. They called this: “Infinity+1
storage plan”.
‘Storage is an important part of email, but that
doesn’t mean you should have to worry about it. To celebrate our
one-year birthday, we’re giving everyone one more gigabyte. But why
stop the party there? Our plan is to continue growing your storage
beyond 2GBs by giving you more space as we are able.’”
Hmmm. I always love that little counter sitting there counting on into the the future no matter what. Sigh. I hope it makes it back.
