The problem with not posting on Tumblr is that the folks in Congress aren’t going to see that. Even if hundreds of thousands of us don’t post, in the end this is still just a microblogging site that they’re not going to pay much attention to.
What we can do to get the government’s attention:
Write to our Congress representatives. If we actually flood them with letters regarding CISPA, they’ll see that we’re concerned. It’s not like they check our Tumblrs constantly, so they’re not going to know when we decide to protest them by not posting. If we write to them, though, it goes to their mailbox or inbox and they’ll see it.
Protest in person. Protesting by not posting on a blog is one thing, but protesting in person gets people’s attention, especially when a big group of you is there together. Make sure you’re seen - and be peaceful about it - and you’ll get your message across better than just not posting on your Tumblr for one day.
Write blog posts about why CISPA is hurting us instead of saying nothing. In this case, we actually need to spread the word, and being silent isn’t going to help us on this matter. If we write about how CISPA is hurtful and share each other’s posts so they’re seen by as many people as possible, we’ll be getting the word out better than if we say nothing.
Let’s get the government’s attention. Make some noise, Tumblr.
