signal boost

Spreading the word, or 'raising awareness' of an issue without actually doing anything useful (like, say, donating money). Popularly employed on Tumblr by image-conscious bloggers who want to look like they care deeply about a cause or issue, while they try to avoid investing any time, money or effort into said cause.

A Tumblr slacktivist reads a blog post from another Tumblr user who doesn't have enough money to pay rent and is shamelessly groveling for money on the internet.

Tumblr blogger: "Reblogging this is as good as giving money, right? I'll just tag it 'signal boost' so everyone knows how much I care about raising awareness and helping others."
