Writing.com is a massive website dedicated to providing an encouraging environment for aspiring writers and hosts everything from short stories, to poetry, to interactive fiction. Needless to say, it is one of the best places on the web to find something to read, or if you feel up to it, someplace to write.
Tropes that apply to Writing.Com:
Author Existence Failure: If this somehow happens, the author's portfolio is turned white with a 'picture' of a feather in honor of their memory.
Bribing Your Way to Victory: GP (Gift points, which are like currency.) are easy to gain by doing reviews, adding to certain stories, logging in daily and, of course, being given them as a gift. However, you'll rarely get more than 100-1000 at a time this way. For $10 you can buy 100,000 GP at the store which will allow you to do a lot more a lot quicker than by simply participating with a free account.
Also noteworthy is the ten item limit for free users. Once you hit ten you can't add any more work until you delete or transfer your old stuff to someone else (at the cost of 1000 GP). Of course, people who pay for a membership get much more room for their items.
Cap: In the interactive stories, the number of continuous chapters is capped at 250. However, for the second and third chapter there are a maximum of five possible choices. The fourth and fifth have a maximum of three choices, and for the remaining chapters a maximum of two possible choices. This means the total number of possible chapters for a given interactive is 5^2*3^2*2^245. Roughly speaking that is about 1.2*10^76 chapters per story. With a new feature of basic membership allowing people to add a third option after the fourth chapter would change the formula to 5^2*3^247, or roughly 1.76*10^119 chapters.
Color-Coded Characters: Gray portfolio icons for non-authors, black for authors, yellow for preferred authors, blue for moderators, purple for senior moderators, red for staff, and white for members who have passed away.
Doing It for the Art: Many people don't care if they receive reviews, awardicons, merit badges, or gift points. They are just happy to have a place to share their writing with other people. In fact, there's an option in the user control panel to keep works secret or only allow friends to see it.
Door Stopper: Many interactive stories goes on for hundreds or thousands of chapters in less than a few months, some other stories aren't so lucky...
Orphaned Series: Whether it's due to Author Existence Failure- or the writer in question simply 'losing interest' in writing, this sadly happens often- if the story has only a 'few chapters' it's also a factor.
Shout-Out: Countless authors include these... sometimes way too many.
Shameless Self-Promotion: A lot of authors do this to their stories, causing a backlog of old stories popping out of nowhere.
This is actively encourage to an extent by the website itself. Every time you make a contribution to something an icon leading to your own portfolio is included. The more you add to other people's stuff the more people will check out what you've got.
Wall of Text: This happens a lot, but most authors (thankfully) know how to properly space out paragraphs.
Zombie Apocalypse: A popular theme in the interactive stories section. The are dozens of these (maybe hundreds or even thousands) of varying quality. Some authors put a lot of effort into the story and establish a coherent universe while others put the reader into the role of a mindless zombie slaying action hero. There are also a ton of fanfiction interactives that center around zombie games like Left 4 Dead or Dead Rising.
