The creating of an account is really quite convoluted.

There needs to be a way to create sub accounts.

Finding content seems to be broken. Typing a search only seems to search for usernames.

Needs a one-click reblog.

What do you mean by "sub accounts"?

Tumblr allows you to log into multiple blogs using a single account. You have a "main" blog directly connected to your account. In addition you have as many blogs as you wish that you can reblog or post to, and can be owned by multiple people.
