Why can't you use the SWTOR site to update people about SWTOR? Why does everyone try to force me to use Twitter? You shouldn't be exclusively using a third party site for stuff like this. It would take 5 seconds to copy/paste to your own forum.
They do, but the also use social media which thousands if not millions use these days to update those who don't get the notice from the site because shocker not everyone visits this site for information, it's actually a small portion who do. Having it multiple places makes it so that the word gets out, I for one have them followed on twitter for this exact reason. Their site may go down and have to do emergency maintenance, I can then go to twitter and see they are doing it.
Options are good.
