I don't think it's to make people come back and read you - people read your blog because:
- they like you already;
- they're related to you and this is the only way they'll know what you're up to (Hi Pepe! Hi Uncle David, Rachael, Denise, Mike, Rachelle!);
- they hate you and are eagerly awaiting your demise;
That being said...
I have good news. I can't tell you about it right now. Come back in a month and all will be revealed! (Here's a hint: it involves chopsticks, sea monkeys, two bottles of Rebel Yell, and a move.)
