Check Your Links
Some links go dead - stone cold.
I just found one of mine posted on a number of sites that is no longer in effect because the affiliate program terminated at the begining of the month.
Now I have a job to do tomorrow. I will need to replace those because nothing is as discouraging as clicking a dead-end link (well - some things are, but not in linkdom).
Keep your links fresh and it will reflect care and relevance in your blogging.
