With yesterday's announcement from AOL about 5GBs of online storage, the to-be released Windows Live Drive and rumored Google GDrive, all the major players are making strides into providing large amounts of persistent and easily accessible storage to their users.

Except Yahoo! - they've had a storage service forever - Y! Briefcase, but it is dwarfed by these recent developments - 30MB free, upgradable to just 100MB for $35, and a very Web 1.0 interface - no AJAX in sight.

It's not like they are not running large disk services for the backends of several properties - Y! Photos and Flickr offer unlimited storage for image files, so it's not a stretch to imagine them having the capacity to compete if they want to.

So Yahoo!... where's your offering? Is this a game of catch-up like when GMail opened the floodgates on 1GB+ mailboxes, or a case of Yahoo! forgetting an older service and letting it wither away??
