With every social media platform there are some good and bad points to using them. For Twitter they are:
Here are a few of the common Pros of using Twitter:
Useful for networking
Good place to share blog posts
Tweets can boost your SEO
Great way to get advice
Easy to use
Now for a few Cons:
Tweets don’t last long
Takes time to maintain presence
Trolls can be common
A lot of spam accounts
Bad news can travel fast
So when it comes Twitter its up to you whether you use it or not. It all really depends on what you want to use it for and if you can handle the limited characters that you need.
I personal think its a great place to share blog posts, informative posts, show off your art or ask for advice on a topic.
