I don't think twitter expires 1 day old tweets though
I've been able to see postings in my twitter feed from over a week ago...
I can do a search and find stuff that is weeks old...
I wasn't one who posted about it being down, but searching @eevblog I also cannot find any single tweet about the site down

Lots of tweets '@eevblog user xxxxxx liked a video on youtube' and '@eevblog user xxx favorited a video on youtube' - where does that come from? Although I understand as a content producer that helps bring viewers and thus revenue, but it's also one reason why I hate social networking.. I don't need to post to the world whenever I favorite a cat video, or like something that might not be aligned with another person's viewing tastes... yet we are often tricked and/or misled into posting these things.. i.e. just signing into a third party website using the convenient "log in with Facebook" or "log in with twitter" often ends up giving implicit permission for the website to impersonate you and post to Twitter or write on your Facebook wall about everything you do on their site. And often you don't know you are doing this until its too late... and you have to hunt hard to find out how to opt out of this tactic.
I don't use Facebook. I do use twitter, as a convenient way to keep on top of stuff I am interested in, but I post very little.
