Due to the fact that linode provides unmanaged servers, it would be next to impossible for them to provide web counters.
That said, I can offer another recommendation for webalizer - I've used it in the past and it does a decent job. I've recently switched to using AWStats, which, like webalizer, is a local access_log processor, but I think it gives some more detailed information.
I've also used
Google Analytics on a few sites - it's a free web stats service. They don't force you to use any ads or anything ridiculous like that, and the stats they provide are quite detailed. All you need to do to implement Google Analytics is to add a small javascript snippet to the <head> of each page on your website. If you're using a CMS, this is quite easy, as you'll only have to edit the master header template file.
