I'm just wondering if I should set my blog to private since I still have a few more months of building to go. Google has already indexed some of it but things are changing daily so I'm wondering what would happen if I changed it to private at this point. Will the google gods get upset with me? lol. Thanks.
I don't think it matters much either way. The pages that have already been spidered will remain in Google's index for about 90 days anyway.
Just leave it public since it's already there. You'll continue to build a nice history, especially if add content along the way.
The truth is, no one is really going to be able to find it anyway if you don't do any promotion.
