I want to add a header to my "blog entry" content type that will have a couple icons for sharing with Facebook, Twitter, email, and Google +1.
How can I do this?
I currently have the icons in a block in the sidebar.
Below are some alternatives to pick from (quotes are from their project pages).
Integration with the ShareThis social bookmarking utility on selected node types.
The code for this project was based on the original share project for Drupal 5.x. The code for this project has been trimmed down to only work with the ShareThis system, and not require any additional modules to work properly.
The services included are various: del.icio.us, Digg, Facebook/Facebook Share/Facebook Like, Furl, Google Bookmark/Google Plus One, IceRocket, LinkedIn/Linkedin button counter, MySpace, Newsvine, Reddit, StumbleUpon, Technorati, Twitter/Twitter widget, Yahoo Bookmark, and many more, they are split for language in different packages: basque, dutch, farsi, german, hungarian, italian, polish, russian, spanish, swedish.
Other services are availables to be included within an extra module which can be built easily through a web interface.
The Drupal Sharebar module lets you easily add a "floating" social media submission bar on your website (like that found on Mashable) that includes share buttons for the most popular social media websites online such as Facebook, Twitter, and Google +1 Buttons.
Share buttons for Drupal including AddToAny's universal sharing button, Facebook, Twitter, Google+, Pinterest, WhatsApp and many more.
Large vector share buttons use AddToAny SVG sharing icons. AddToAny vector icons load efficiently, are mathematically precise, scalable to any size, and stunning on High-PPI screens such as Retina and Retina HD displays.
Despite a bunch of other social modules, this module fits exactly if you want simple share buttons without worrying about messy configurations.
Easy Social is available both as blocks, attached to nodes, comments and also as a Views field.
Follow adds sitewide and per user links that link to various social networking sites. The links reside in two blocks. The Follow Site block lists all the links for the site itself, and by default is visible on all pages. The Follow User block lists all the follow links for the user and is visible only on user profile pages.
Provides an AddThis.com button or toolbox to let your users share your content to social network sites.
The Social media module helps integrate your website with social media sites such as Twitter, Facebook and Google+. It provides an centralized way of managing social media profile information and plug-in widgets such as follow and share buttons.

I recommend you to make some tests with visibility options to understand how it works.
Hope this helps!
