Let’s see…

1. Google makes the means of viewing one’s “toolbar pagerank” available to pretty much anyone. You can view it through part of the Google Toolbar, or you can use a website such as http://www.checkpagerank.com/

2. PageRank applies to individual pages generally, but most people are concerned mainly with the rank for their main page (e.g. http://www.webmaster-source.com/).

3. There isn’t exactly a standard “good” PageRank. Huge sites like Apple.com (which has one of the highest ranks ever: 9) get tons of links in, but they pretty much don’t link to any other sites, hence the great rank. The top blogs (see technorati.com/pop/) have ranks like 6 or so because they do plenty of linking, but they’re so popular they have a ton of links coming in as well. I’d say for a blog that’s been around for less than a year 1-2 is what you can expect to have. PageRank 2 is a decent ranking, though this blog only has a rank of 1 because I do a lot of linking. Really, you shouldn’t worry about PageRank that much. Focus on building a reader base, and making that “Subscribers” counter go up.
