I've been giving some thought to this, and have blogged here: http://ebidwidgets.tumblr.com/post/1...ocial-networks
It's a bit long, but for those who prefer not to visit blogs or leave the forums it boils down to:
- Don't make more than three marketing posts at a time.
- Make sure your images are top-notch.
- Add value with good text.
And if you want to know more than that, read the blog, I'm not repeating it all again.
Comments there or here welcome, I don't expect everybody to agree!
