Finding who is writing about you is not that difficult :)
Ther easiest way is Technorati.com - it shows links to your weblog from homepages of other weblogs.
Next to it many people can see their referrer logs - pages that bring visitors - but it depends on a software/hosting you use.
And, of course, there are many options for "egosurfing" - seaching for your name/weblog title/url in whatever search engine. Google may do, but to fins blog specific references you may want to use search in Bloglines or Feedster. The best thing about the last two is that you can subscribe to a search via RSS and be notified when someone mentiones you... Finally, there is PubSub. It gives search results only in RSS, but if you can manage it (as well as complex search arguments) you can get links from all weblogs mentioning something of you. I like this one most :)
