Update (moments after Publishing) – Here’s what the following WordPress post looks like when pushed to Tumblr:
What this blog post looks like when pushed to Tumblr using WordPress’s new option in the “Publicize” feature.
I just read a couple articles about the new integration of a push-to-Tumblr option for new WordPress blog posts. This may be helpful for museums who’ve established a large following on WordPress, but want to share easily with the growing community on Tumblr.
Caveat: I don’t ever recommend sharing with a community that you don’t check in on. If you’re posting on Tumblr, but not checking to see if you have messages, reblogs, etc. there, you’re not really part of that community at all. The obvious analogue for this is the infamous pushing of Facebook posts to Twitter!
The one thing which seems to be missing is a preview feature. I’ll test it out with this post and see how it looks. Apologies if it’s incoherent, but here’s hoping it looks clean and works well. Articles:
“Earlier today WordPress.com turned on the ability to push new blog posts to Tumblr, alongside the existing capability to do so for Twitter, Facebook, et al. This is interesting for a few reasons….” – Matt Mullenweg
“The second you publish a new post on WordPress.com, you can instantly share it on Facebook, Twitter, Yahoo, LinkedIn, and now Tumblr with a feature called Publicize. This helps you get exposure to multiple audiences without having to manually share your content on all your favorite social sites.” – Justin Shreve (WordPress)

Thanks for sharing this info. Had not really found a use for Tumblr, but I see I can make it work without having to spend an hour readjusting pictures and the like. Thanks MuseumNerd, you are always cutting edge!
