Apart from the fact that you yourself will learn a whole lot of new stuff hunting for and reading such articles, you'll start to get known as someone who shares high quality information and more people will follow you to get hold of it.
There's another benefit. If you share the blog post of a well known blogger, then your tweet will often automatically include his Twitter handle. He'll see that as a mention when he next logs into the site. And will probably look at your Twitter profile. He might follow you, and retweet some of your tweets. Better still, he might even link to your blog from his.
