I've been using Blogger to all my post publishing needs for some years now. And since I moved my "home" into a Mac OSX system I've started using ecto to publish to them. But I've stumbled in this issue in more than one blog, so this post serves as both advice for the frustrated and to remind me in future installations (never googled your blog to see what your past thoughts were? you are missing out, then!)
Problem. I write a text, such as this one, with some paragraphs. and if I publish them as is, blogger spaces them out, inserting linefeeds (<br/> HTML tags) between them. So I desperately try to fix them in ecto. I refresh the posts list, and see the extra spaces. If I fix everything, I get the same result. If my mind wonders and I forget to fix something, and still publish it, I see not one but two extra line breaks. Wow! :)
Solution. Taken from an ecto's support forum entry the idea is to make Blogger *not* insert linefeeds in every return on the posted text. ecto does that job already, so we simply stop Blogger for doing extra work. Who knows, someday ecto will detect that automatically and won't hurt our posting confidence in the process :)
Details. Go to your Blogger dashboard, see the Settings tab, and the Formatting subtab. Set "Convert Line breaks" to "No". Save. Publish. Rejoice!
