Jedi Sidewalker made a clever observation on his blog recently, that the most successful blogs all have an adorable pet or familiar that follow them around, increase the 'awwww' factor and keep readers looking out for their adventures.
Now I, personally, am not above a gimmick to draw and keep readers. MrsB has Tanner, CrazyMom has her nearly endless stash, and I have Iggy.
My long-term readers (hi, sis!) may remember Iggy, and the half hour when I thought I might sell him, and my firls may well remember his adventures in trying to have his own book. Now, he will have a career inhabiting my blog - his first adventure arrives tomorrow.
