Should we take ads?

I want everyone's views on this (including our many "visitors"). Should we take averts on this blog?

Google - who run the service on which it is based - offer a service whereby "relevent " adverts appear on the blog (in a descrete column or banner - no pop-ups), and from which we would derive some sort of income via click-through.

We can also put in specific ads of our own.

Now on the plus side this means money. Not much, but something. On the downside it means clutter and a lack of direct control over what is actually advertised (rugby- and sport-related links will dominate I expect, but I'd be slightly worried about what the advert engine might produce if it picked up on combinations of words like "girls" and "mud". For example).

To get an idea of what we are talking about here see http://www.google.com/services/adsense_tour/

What do you all think?
