Absolutely. Google webmaster will show you all links, including ones that google places little or no value on. You should compare the number of backlinks google shows with the "link:" command with other sites ranking for the keyword(s) you are targeting. All though the number will likely be a lot less, it's relative and should give you a better guide. Google is about "quality, relevant links" not a mass number of links.
Only my DP profile shows up when I do that. I have many high PR links that are relevant to my site but don't show up...
