Yes this is normal. You probably just happened to launch your site in time to catch a mass PR update. Since Google couldn't find many backlinks, they only pushed your PR up to PR0.
I was kidding, I wanted know do you think it too. Man, it`s normally to get PR0. I have my Travel Blog for 3 days and it`s PR0.
No PR is a site that has not been through an update (not in Google's index during the update) and a PR0 is a site that earned a 0. Just keep in mind that PR is useless and has nothing to do with what's important...the SERP's.
I had pr1 within 10 days of getting my site ready....It's reverted to its original place now though..No Pr lol
Google owns Blogspot, so definitely they will prefer to index and rank their blogger's site first if they post unique content
10 days PR-0 is a good achievement - shows that you have been indexed fast enough. Now for you to go and keep building.
