1. Storybird
This is a very interesting site mostly targeted at adolescents who create beautiful works of digital art or fantasy stories. It can be used as a platform for teachers to make up assignments for their students. All work is strictly monitored by the site’s moderators including the comments section. There are monthly writing contests with very creative topics. As an adult writer, you can still enjoy composing a new story, first by selecting an art image, then choosing to write a long form or picture book. The atmosphere is really friendly and interactive.
Cons:
No adult content or graphic acts of violence can be described in your writings. This can stifle many authors’ creativity and potential. Since the content has to go into moderation, it can take a month before it is public on Storybird. There isn’t a category for nonfiction material.

2. NoahWriting
As a new member, I love that this website covers any topic the writer is willing to write about. There are 24 categories to choose from, including general, which can cover anything. There is even a small media gallery to attract viewership. Once you submit your work, it will be public under the recent category instantly. There is incentive to win a monthly award, depending on quality and the popularity of your contributions.
Cons:
Viewers seldom give a ‘thumbs up/like’ or leave comments. We are not as interactive with our feedback for one another as we can be. The media gallery has a very limited number of images. Noah Writers are outstanding and well researched, but as the website is a nonprofit educational fund, it is not as attractive as other sites, although the content more than makes up for it.

3. iWriter
In this journalistic website, you can get paid for the articles you write for clients. You can also pay to have content written for your business. There are Elite Plus, Elite, Premium, and Standard writers, depending on when you joined, your talent and whether you are a paid member. This site is nearly identical to Textbroker. The articles requested can cover any topic that a business might want you to advertise or inform about. You only get a few hours to write an article you have selected, so you need to do your product research extremely efficiently.
Cons:
It can take a great deal of time to reach the level of a Premium member, after writing 30 articles and having a very high client approval rating. Once you are prepared to write content, you have to make your selection fairly quickly, as all the members of the site are looking to pick up the same pieces. Some client requests get snatched up within minutes of viewing it. You need to be very focused if you are seriously looking to earn a few extra dollars here.

4. Wattpad
This is an excellent community of established authors who are looking to test the waters before releasing their latest novels. I would consider this site to be close to iBooks or Amazon, but free. There are endless genres to read from, sure to interest any reader.
Cons:
In order to post your own publication, you would need to have your book complete and ready to submit. I have not seen authors submit chapter by chapter as they often do on other websites. You are also responsible for your own book cover, whether you decide to buy it from another site or create one.

5. LascauxReview
I happened to stumble upon this site due to its beautiful Renaissance Era art gallery. It contains the categories of fiction, poetry, and essays. They have ongoing contests with prize money. The art alone can inspire anyone to write a romantic tale set in a castle! The writers here are very poetic.
Cons:
Because the monetary prize can be high (up to $1000), you have to pay for submission from $10-$30. You are allowed to submit up to 5 files at a time, so again you must be finished. There is just one small category that allows you to upload for free, which will only receive some mention if there is positive feedback on the LascauxReview.

Please let me know about any writing/blogging/art platforms that you yourself like to use.
