Blogo is a great Mac blog editor for WordPress and Blogger. If you don’t want to write using your browser you should take a look at this app.
I’m not sure why you wouldn’t want to use a browser to compose your posts. Mac Apps don’t really offer any one feature that can’t be done via the browser. Maybe you are old school and you just don’t want to write in your browser. Or maybe you want an app that is running locally for when you don’t have an Internet connection. What ever your reason this is your app.
The app does a good job of allowing you to insert images. It has a nice image editor which allows you to quickly crop and set the size on your images. It also allows you to show a placeholder for images so that they don’t distract from your writing. I like this feature a lot because images are distracting.
Not really sure what else to say about this app. Its good if you like apps and you blog on WordPress. Also I wrote this blog article with the app. You can download it here.
