Along with the people of the world communicating directly with the other people of the world, Blogger hosts some people of very questionable character. Various criminals are using Blogger, to host blogs containing material dedicated to hacking attacks, and to distribution of porn and spam. Not so long ago, if you used the "Next Blog" link in the navbar more than a couple clicks, you'd get an eyeful.
Last week, Blogger took a major step forward, and eliminated the hacking, porn, and spam problem in "Next Blog".
Between that change, and the overall styling and content change made to the navbar, made earlier this month, I see a major improvement in making BlogSpot a place where people of all ages can surf, safely.
