"Twitter is stepping up its actions to fight spam, which has been plaguing the site since earlier this year and appears to be spiking this week."

The company is looking to hire a spam engineer, preferably one who has worked at a big search or e-mail company, according to a tweet by founder Evan Williams.

"When I look back at the dotcom apocalypse that was 2000 – 2002, I realize some of the best companies I've ever been involved in were created during that time. In the midst of this, I remember the endless stream of "the Internet is over" and "the information technology business in now a mature business and there will never be innovation again." Yeah – whatever.

Get some exercise, take a shower, eat a good breakfast, and get out there and build a great business."
