Some of the biggest bloggers use Blogspot/Blogger. The Sartorialist used it for years, as did Fashion Toast (both have since migrated off). Face Hunter, Man Repeller, The Glamourai, Keiko Lynn, Where Did U Get That?, Natalie Off Duty… the list goes on and on. In fact, IFB used to be on Blogger, and my original blog, also on the same platform. I also just went with the first blog platform that came along, and what blog platform that it looked like most people were using at the time.
While I used to say “use whatever platform makes the most sense to you.” There are reasons why I moved from Blogger to WordPress, and it's not because there's that one magical platform that will make your blog successful. After being on WordPress for a number of years and experimenting with Tumblr, I revisited Blogger and was surprised.
Decent Themes Are Hard to Find and Hard to Edit
On WordPress and Tumblr, there are loads of themes on the web, Tumblr has fantastic customizable free themes, but if you want something special, it even makes it easy to browse through premium themes and you can test out the support. WordPress is a more robust system, but with WooThemes, Thesis, and StudioPress you can pay a fee (usually around $80… but when you factor in the headaches you avoid with the support it's cheap). If you want to add ecommerce to your site, there are WordPress themes you can look into to make the process of setting up your blog's shop a heck of a lot easier.
When I went to Blogger, I couldn't believe that they haven't updated their themes/templates since I had last used their site in 2008. That's almost four years ago. I remember that I learned how to code because of the amount of work I had to put into my Blogger blog. Also, I tried looking for new templates from external sources, and there weren't any themes I could recommend. The designs were clunky, expensive and didn't appear to have much support.
Blogger May Shut Down Your Blog
It doesn't happen often, but remember when Blogspot thought Wendy Brandes's blog was spam and shut it down? She started this blog while dealing with the debacle (and has since moved to WordPress). It also happened to Food Fashion and Flow, who one day found her blog had been deleted, and her username had been marked as spam by Blogger, even though she has original content.
One of the biggest reasons for using WordPress (self-hosted) is that you have control over your content. You can backup your content automatically with a simple plugin, and no one is going to shut down your blog, except maybe your hosting company. Even then you can contact them and get your blog data back so you can at least move it to another host. Not so with Blogger.
You'll Probably Move to WordPress Anyway
For many bloggers there comes a point when they move to WordPress. For it's functionality, you can a mobile version with a plugin, add forums, even social networks (BuddyPress), eCommerce, and the multitudes of beautiful magazine themes, you can really create robust websites off the platform. And believe it or not, with it's support system and once you get the hang of editing your style.css files the possibilities are endless. Whatever your career is focused there is probably a WordPress plugin to help make that happen. So why not start off on that platform? Tumblr is also great, but getting to know how WordPress works from the beginning will only help you imagine the possibilities in your blogging career.
