Writers of faith need to have some outlets that get them reaching out to other people of faith. Here are a few places where you may want to post comments or status updates, even join similar groups. I do not consider this an exhaustive list by any means.
You have to get on www.youversion.com (created by lifechurch.tv). I love it and get some great feedback when I add link or text contributions and bookmark Scriptures. There are faithful folks on the site worth following. I like Shoutlife and its author groups, too.
Try www.wordpress.com or www.blogger.com for blogging. Great stats and data for bloggers. Even if you use Blogger or some other blogging platform, you can import posts into Wordpress. I do so with http://revbruce.wordpress.com via the Ministry Mechanic with Blogger imports and FeedBurner.
Consider using www.twitter.com or www.linkedin.com to connect with other authors, post links to your work, or just share/ tweet random thoughts and words of inspiration.
Look into using a site like www.articlebase.com , www.bizsugar.com or www.helium.com to write articles on topics related to faith or your profession. Get feedback and keep working at your craft.
