Do not wait to get your Pillowfort accounts. Do not wait to post where your followers can find you. Do not hesitate to reblog your contact info five times to ensure everyone sees it.
Do not stall on following those exact links and friending people. Even if all you do is that, sign up on a site and friend people, get it done and get it done soon.
I’ve been through Strikethrough and Boldthrough. I watched del.icio.us break with zero warning overnight. There is nothing more stressful than the after-the-fact scramble when you didn’t have warning and everything goes to shit and you have to salvage it.
Get your info up, and make sure you have followed the people you want on other services. Hell, I have a few friends I only know on Tumblr, and I plan on outright asking them for their infos. I don’t want to lose people.
This may finally be the start of another mass fandom exodus. It might not. Be prepared for either eventuality.
So, @story-kat got hit by the blog termination fuckery now plaguing this hellsite. She’s already contacted tumblr about it and is working to have her blog restored, but I wanted to let everyone know because we share a lot of followers.
