I have noticed that some people that tweet will post a link to the article they are referencing and then #xxxx(a category). I finally figured out that was a category after looking a different tweets. I didn't realize Twitter had categories and that you could look things up by categories. Is that what this is? And what is the advantage to adding a category to my tweet?
I also notice another thing when I entered a category in the search. While looking through the tweets on the first page, most of them referenced the same article. But they did not retweet the article. They shorten the article with bitly and tweeted it. However, the article did say it had been retweeted over 100 times. But, the posts I was looking at didn't show they were retweeted posts. Isn't that like stealing an article.
I'm confused. I always retweet if I like an article and think it is relevant.
