Google's Postini clogs email

Google's Postini e-mail security and spam filtering system is seriously clogged, with businesses on both sides of the Atlantic complaining the hosted service is slow to deliver their messages, reports The Register.

Google has acknowledged the problem, but it prefers not to call it an outage and indicates the problem is limited to the US.

"We're aware of an issue that's causing a delay in mail delivery for some Postini customers in the US, and are working to fix it as quickly as possible," reads a statement from the company. "We know how important mail is to our users, so we take issues like this very seriously, and apologise for the inconvenience."

Facebook and Twitter are in, MySpace is out, according to Experian Hitwise. The Internet monitoring company reported that Facebook, the top social network in the US, grew its share of all the visits to social networking sites from 19%, in September 2008, to 58.6% a year later, states CNET.

That's a more than 190% increase. Over the same period, Twitter's share jumped from 0.15% to 1.84%, and the service now ranks as the fourth largest social network.

Ailing MySpace, which is scurrying to remake itself into an entertainment portal, is still in second place behind Facebook, but scores of users have begun walking away.

Standardise, simplify and automate. These three words are at the heart of a strategy laid out this week at Oracle OpenWorld 2009, in San Francisco, by Michael Dell, says eWeek.

Dell, CEO of the company that bears his last name, says he wants to battle inefficiency and reduce IT spending with what he called the "efficient enterprise".

Dell has spoken about the efficient enterprise in the past, but this time he announced the company would aim to slash IT spending by $200 billion per year by focusing on ensuring enterprises get the most out of their technology.

Twitter has unveiled a tool that makes it easier to report suspected users, reports PCMag.

"Click the 'Report as spam' button under the Actions section of a profile's sidebar and our Trust and Safety team will check it out to see what needs to be done," Twitter's Jenna Dawn wrote in a blog post.

Before concocting a devious plan to get someone kicked off Twitter by reporting them as spam, Dawn stressed the tool will not result in some sort of automatic action against the suspected spammer. Instead, it will simply block the person from following or replying to you.
