Is a Weebly blog pointless?

Does this seem like a sensible blog format? Or is the mighty superiority of WordPress obvious to everyone except me?

Discuss!

Will I hate this format once I decide to add fancy schmancy widgets? Are there deep flaws to Weebly that might only be apparent once I've been using it to blog for like five months?

I don't have a ton of spare time to waste tinkering with the way a blog looks (if I'm going to waste time, I'm going to waste it writing!). This Weebly thing seems so easy you could train a precocious cuttlefish to use it.

So what do you think? Have I already made a huge mistake by choosing this particular format for my virtual sandbox?
