I started on Wordpress and I'm glad I did. I used to use blogger for other blogs I wanted private, but if you want a blog to be known, Wordpress is the way to go.
I don't regret anything as I *try* to remain somewhat anonymous for my child, which is why I don't write down her name in the blog, in case she's older and googles her name and sees a blog about how her butt had a nasty rash ;)
The nature of blogging is to speak in your own voice...the best advice I ever got from another professional blogger was to be as opinionated as possible and find my voice...."not everyone will love it but some will and those fans that find you, will be the ones that stay, the ones who share & support your work and that's why you write"
I never looked back after that....so speak your mind and never stop & the people that come back will come back because they love the sound of your voice....probably because it sounds like their own!
Think the biggest mistake I have made (and apparently still make) is telling it how it is. People don't seem to like the truth, for whatever reason... Oh I know. Denial! But yea. It's killed my readership but I still do it :P
When I first started I was all over the place with my posts, no specific focus. I think it helps to have focus and make what you write about matter to you.
Fantastically great post! Perceptive yet entertaining as well. Thanks.
