Recently it has been announced that Google is to stop allowing people to block websites from their search results.
I have a couple thoughts on why this might be the case;
- Sites that pay Google lots of money in advertising are being blocked and that probably isn't good for business.
- Their suggestion is to download a Chrome extension, which of course requires that you download Google Chrome.
I can't imagine there is a huge technical overhead in supporting the functionality and it is useful functionality, so I don't think it could be because the functionality isn't being used.
