It's very important for SEO (search engine optimization) to have a meaningful blog post URL in your Blogger or Blogspot blog. Blogger will create a post URL automagically using the post title. So, if my post was titled "My post about iPhone programming", I would see a URL like http://blog.daveworld.net/2011/07/my-post-about-iphone-programming.html.
But sometimes this plan gets thwarted by the length of the title. In fact, if your title is over 40 characters, there's a good chance the URL will be truncated to something that is NOT satisfactorily search engine friendly.
For example, my last blog entry was titled "How To Follow More Than 2000 People on Twitter". You can see it here.
If you are using Twitter and are trying to follow more than 2,000 people, you may encounter the following message:
"Your account may not be allowed to perform this action. Try logging out and in again."
Do not despair. What you need to do is get more followers. When you reach around 1850 followers, then you will be able to follow more users.
So, you may want to unfollow some people you are following who are not following you back.
I use a tool called TweetAdder to help manage my Twitter followers. It helps me find users who are interested in my Tweets through targeted searches, and it also helps me unfollow users who are not interested in following me back.
