Well in this post, I'm not going to tip. Instead I'm going to send you off to Kaz Delaney's blog as she has a thought provoking and good post on 7 Reasons for Not Blogging.
And read the comments as well as there are more interesting points made.
Thanks Kaz. You've saved me writing a blog post :)) But really you know me and sharing what's around the net, so there you go.
Happy reading all.
