To answer your first question, we answered a very similar question very recently.
We’re in the planning and prototyping phase right now, so we don’t have a lot of details to share. But we will share our plans and progress as it becomes clearer.
Some of the pieces we’re discussing are:
- Mapping Tumblr database schemas to WordPress.
- Supporting Tumblr themes natively in WordPress.
- Ensuring fast response times for all feeds.
To answer your second, we can say that we have looked into this several times in the past, but it is a tricky problem that requires some careful work. There are a lot of assumptions baked into Tumblr about how primary and secondary blogs work, and it would be particularly difficult to switch them around. It’s also not something we’ve had a chance to prioritize, in recent times.
We should also use the opportunity to clarify that, besides a bug or two here or there, how you know and use Tumblr will not change!
We hope this helps. Have a great day!
