PriceWaterhouseCoopers has produced a report, via PaidContent.org, which provides advice to media companies and telcos on how to organise in a Web 2.0 environment. There is a link to download the report.

John Battelle finds some evidence of Google’s plans with Google Base – new interfaces for specific purposes like this one for real estate.

Update: Steve Rubel finds the same for cars.

Jeff Jarvis rehearses the arguments for and against enforcing registration on blog comments. On balance, he comes down on the side of open access, but with some reservations.

According to a report from the AOP online search revenue was 56.2% of the £1.4bn online advertising market in the UK last year. Online is now taking nearly 8% of all advertising pounds.

Flagr is a new mash-up which allows users to send in a description, address and comment to [email protected] from their mobile phones and which will then instantly put a flag in the map at that point. If you include a picture, that will appear too. As they say: “bookmark the real world”.

Curiously-named Sacredcowdung has a list of “All Things Web 2.0” – and very comprehensive it looks, too.

Something I’ve not seen before: the “view ads about” box on the meta-search engine gada.be. Try it out.

Update: on the face of it this is a really trivial idea (although clever enough in its own way). But if you think about it for a moment, there are some interesting implications.

Because gada.be isn’t a publisher, it doesn’t have the same preconceptions about the value of advertising that publishers do. If the targeting in Google ads is good – and we know from experience that it is – why wouldn’t you want to search just ads instead of content, especially if you were looking to buy something?

Publishers have long published lists of featured advertisers in magazines, but this is not really much of a reader service, more a sop to the advertisers. The fact is, we’ve never invested time in classification of ads to make them really useful in this way, largely because we don’t see them as information. Google (and gada.be) doesn’t have the same mindset.

eQuake Alert is a Firefox add-in which will alert you with basic information everytime an earthquake happens somewhere on earth. Better still, it shakes your browser in proportion to the severity of the quake!
