I'd say mainly it's nice seeing your data in the new blob sidebar panel next to sqlite data and the code that uses both. But also from the blog post:

> Scope blob storage is isolated by val, rather than by account. This simplifies things for when you might need to transfer a val from one organization to another, or list only the blobs that were created by one specific val.

> In the old days (before yesterday), blob storage was scoped by your user account or organization. In the rare case that two vals wanted to access the same blobs, this was nifty, but in the more common case we'd see vals accidentally overwriting each others data. And there was no connection between a blob and the val that wrote it, so you couldn't transfer a val without losing access to all of its blobs.
