When you take the time to comment and add to the conversation, I think you should include related links, including those that are directed to similar postings of your own. I am not alone in this opinion. There are many blog postings that explain why it's important to add appropriate and active links when commenting. This is a typical point about commentators linking through there comments:
Many bloggers (myself included) believe that good comments should be rewarded with a link back to the commenter's site (if they so choose to include one). However, the way you go about commenting and including a link will clearly demonstrate whether you are there to contribute or merely to take.David Wallace, of SearchRank.
When commenting and adding to the educational professional development conversation, I hope you will use the .html that will give you an active link here on this blog that refers to the blog or website you are quoting. Here's how to insert the url and name of the link you want to activate:
Why do I hope you will do this? I want to continue the conversation. If your link in your comment is not active, most people will not take the time to copy and paste your link. We all benefit from your investment of time to learn this little bit of code used in Blogger, because your links will be active. Readers will have an opportunity to learn more and continue the professional development conversation. That helps all of us improve our educational practice which directly improves the educational experience of students as well.
The caveat is that many other blogging platforms use a different snippet of code, but you can learn these also. The more you practice adding active links, the more effective you will become in adding value to each conversation. Isn't that one of the reasons why we collaborate in our Professional Learning Network?
