As always my plans to spend a weekend dedicated to catching up, and even getting ahead, on my blogging etc seem to have been destroyed before Friday is even over, thanks to a horrible noise from the exhaust on my car. I guess that’s what you get for buying something cheap and unusual!

And that clumsily links into the amount of change that’s occurring at the moment to major sites:

New look Facebook has been talked about a lot, and it’s now available. And to be honest, I’m really undecided about the design. It certainly makes it more blog/lifestream than profile page, and it moves applications out of the way, which is good for dealing with application addicts. I’m surprised the advertising is moved out to a column where it is easier to ignore over time, although it did catch my eye the first time it logged.

And there’s new look Delicious. Notice the lack of del.icio.us, as it’s now become www.delicious.com, as they were seeing all sorts of versions of the name being used. A bit of a shame in some ways, as it was one major way to stand out from the crowd. Ma.gnolia might feel a bit silly now! Again the design is cleaner and more modern, and a little lifestream-esque.

And you may have heard the tiniest of whispers around the web that tiny new startup Google is being challenged by a new search engine called Cuil, which claims to index more pages than Google, and return more linked results. One interesting ploy is that they promise information for each search will be anonymous – fine in theory but what will happen in the event of a court case? At the moment, returns a bit flakey, like this one for Dan Thornton. But I’m going to give it some time before making a judgement – I was initially unimpressed with Mahalo, but I’ve grown to like it more and more as time goes by. The best thing about Mahalo’s human-powered search is that the official plugin allows you to display an information box alongside your Google results – meaning it can save you a few clicks if you’re researching something which is covered.

And rounding off a pretty quick skim, is the news for social media marketing, research and business people that Forrester has bought Jupiter Research, which is pretty big news in that space.

Now if I can just stop the exhaust falling off the car, I might be able to catch up with a  few things.
