It is always a good thing to have as many readers as possible on your blog. To increase the number of readers it is important to make it easy for them to both follow your blog posts and share your posts on social networks.
I will show you how you very easy can add icons with links for rss feed, twitter, delicious, stumbleupon, technorati and digg.
I have chosen to have the RSS feed and Twitter icon on the top of my left side bar. This is how you do can do this in WordPress.
Insert in the very beginning of sidebar.php
<div style="text-align:center; padding-top:5px;"> <a href="YOURRSSFEEDURL"><img title="Subscribe to my feeds" src="RSSFEEDICONURL" alt="Subscribe to my feeds" /></a> <a href="YOURTWITTERURL"><img title="Follow me on Twitter" src="TWITTERICONURL" alt="Follow me on Twitter" /></a> </div>
