I recently started a blog for a very specific niche and I know little about Blogger beyond it's affiliation with Google.
Should I allow nonregistered users to comment on my blog? I'd like as much user interaction as possible but I don't know the risks. Is there a significant risk of spam? I know I can moderate users' comments, but I'd really rather not play policeman. Ideally I would like to allow comments without my approval but have the power to later delete them at my discretion. Is this or anything like it possible?
