I've just had a little game of 'blogging leapfrog'. It's simple enough if you want to play.
1. Go to a blog that you follow.
2. Find where they have a list of blogs that they follow.
3. Click on one.
4. Repeat steps 2 and 3...as many times as you like.
It takes you to some far flung places, and some not so far as well. The only problem is if you get to a blog where they don't have a list of blogs that they follow on their actual blog. That tends to stop you in your tracks.
And I've discovered a 'glitch in The Matrix'. On a couple of occasions I have been leapfrogging and have arrived at a blog that I find I like. I've clicked the follow button. It then prompts me to sign in to Google Friend Connect...but then won't let me sign in.
However if the blog in question has a 'follow' link at the top, up there with the 'dashboard' and sign in/out' buttons, then it lets me follow the blog straight away.
And Googling the problem only brings up people who are having the same problem...no solution.
But then I gave up looking pretty quickly...maybe someone with a higher level of patience when it comes to irritating problems would have better luck.
