I started using Mippin a few months ago but it's only in the last couple of days that I've been a regular user.
I'm finding that it's the best way of keeping up to date with the current state of the mobile internet. I've added my favourite mobile sites and I now have an up to the minute snapshot of what's happening out there.
While I still use Google Reader, I prefer Mippin because the user interface is better, allowing you to manage subscriptions and adding Mipplets to your start page brings in content that I would never have seen.
If you want to follow Snowbabies on your mobile, Mippin is the way to go.
