Actually, that depends on HOW you blog. If you want to keep a few blogs in hand to increase readership, you can do so and not be penalized by making sure the content on each of your blog sites is unique and original.
In other words, don't use the same post you have in Blogger in your Wordpress site. Duplicate content is usually what gets the red light for search engines, but you can evade it by making sure your content has no similarities between them.
