Thanks to Robin the mystery of the 'missing' blog followers has been solved. It was very reassuring to find that I'm not the only one bereft of followers. Although it's a very minor thing the number of followers on the dashboard does give some indication of whether a blog is being useful, boring or whatever.
This is what Robin found out - just follow the link.
So this means that if you don't have a Google account and want to follow blogs then you'll just have to get one!!!! OR if it's my blog and you don't want to have a Google account you'll just need to bookmark the page or say 'bye bye'!!!!
Thank you Robin for taking the time to find out what's going on!!
