I wasn't really much of a fan of tumblr, from trying it out before and not able to understand what it can do.
But with my trade marketing work at The Filipino Channel, I gave it a try as I needed a non-Blogger (and definitely non-Wordpress, which I don't really like at all!) blog to host content that I was RSS-feeding through our mailchimp mailing list.
So far, somewhat okay.
I still very much prefer Blogger because it's by far, easily the easiest blog platform in the world. But it seems to have a weak reputation among brands that use a blog platform.
tumblr is easy to use, as I found out, but I haven't quite explored it because I'm still much more comfortable with using Blogger when it comes to HTML and creating pages, etc.
