I've worked out a system that allows for sharing photo between Wordpress, Blogger and Flickr. Flickr has a "Blog This" feature which allows for posting directly to either Blogger or Wordpress, which saves time and energy. I've also taken to importing posts from Blogger into my Wordpress blog, which means finding a new audience. Some people never post comments to Blogger, but choose to comment in Wordpress. Frankly, I find it all a bit mysterious.
I use wordpress.org. It's the best. no other platform comes close in my opinion. Blogger is easy to use but if you want your blog to go places then you have to get off on the right step and i think that that is wordpress.
Wordpress all the way for me. I'm not as technically savvy as I would like to be in regards to programming and coding, and the sheer amount of the various add-ons, themes, widgets, and God knows what else that is on offer for people who use Wordpress is very convenient for me. Easy to find, easy to install. I tend to keep my webpages simple, too, so none of the issues caused by lots of SQL queries like mneylon said.
I use ENV2 as my blogging platform. Its by Empower Network LLC and its really good. Its also gives you an automated online business blog where you can build up your business instantly. To visit my blog on this platform its Empower Network - Make Money Online with Asif Ayub
