I have a crappy ass blog and I want to know who, if anyone, is bothering to link to it. Is there a way to cull this info? I did try to google for this first. Thanks for the help.

Ok, this is a pretty terrible answer but:
In theory Google will tell you who is linking to your page if you type the following in the Google search field:
link:<YOUR URL>
for example, I can see who is linking to my game with:
link:www.mariotan.com/lander/
Now the problem is that google is only returning eight pages linking to my game. I know for a fact that more than eight pages are linking to that address… so… so yeah… my post is worthless but it’s a start! 
If your webhost provides Webalizer software, just access your http://www.url.com/stats directory and see the referring sites.
Alternatively, plug in your URL here. This is not comprehensive though.
thanks ya’ll. Know I know just how unpopular the site is.

Another site to try is www.linkpopularity.com
Also, going to www.alexa.com will give you a rough idea of how popular your website is plus it will give you a list of sites linking to yours.
The link: thing on google doesn’t work. My site (which has been indexed for several months is linked to by several other sites, but when I try that it doesn’t show any of them. I emailed google because I was worried that it would cause a problem with how my site is ranked. They basically said that I shouldn’t worry, and if I wanted a better way, just search for sites that contain my web address.
Thanks for nothing, pung!
I just wasted valuable time playing your game instead of doing my work. 
link:yoururl on Google shows only a subset of links to your URL: those pages that link to your URL and have a Google Page Rank higher than a certain threshold value.
For a list of more links to your URL use the link:yoururl term on http://www.alltheweb.com .
I suggest if you want to be exhaustive you try them both. Google gave me three results, and alltheweb gave me three different results.
You can find the links thru google by clicking “advanced search” and filling the inquiry box down aways on page – I don’t know if that gives you the same results as the other method.
Google’s your friend in getting links – pull up the popular sites in your site’s subject, do the find links for the popular sites and SELECTIVELY email those asking for a link.
I’m batting nearly a 1000 for my sites using that method and gotten several hundred links that way. It does take work, I examine each site beforer writing and probably exclude from contact many more than I contact. There’s no need to ask for a link that has none already or sites that appear to have essentially no traffic or unrelated to the topic of your site.
Assuming your “crappy ass blog” is not on your own domain, with your own hosting, and you don’t have access to logs or stats, you can put a free 3rd party counter on your site that will track referrers among other things.
(You could do it anyway, but if you do have your own domain/hosting, there are better ways than a javascript counter)
A response from an expert librarian I know.
I like URL investigator at AlltheWeb <http://www.alltheweb.com>. Enter the URL of the target page and the search results show external links to the page. It may be enough to answer your question, but you should know that different search engines will give you different results because they index different parts of the Web. Consequently, for thorough coverage, you should run the query in the five major engines–Google, AltaVista, AlltheWeb, MSN Search, AskJeeves.
Altavista finds way more than Google. Same as with others, just type link:http://yourURL into the search field
