Why are we all blogging?

Tick as appropriate:

i. To vent one's spleen and let it all hang out
ii. To share one's thoughts and ideas
iii. To impress a community that grows every 3 seconds (as I write this,gosh!that's more often than men thinking about sex!)
iv. To start a dialog
v. To perhaps win friends and influence people
vi. To hone one's writing skills
vii. To explore a business opportunity (hoping that some publisher will
catch the next Dan Brown or... Kaavya anyone??)
viii. To find love
ix. None of the above

Have I left any reason out? Umm...
