1. Size. I'm not going to mention font choice because that's a personal choice for each author, and I don't really much care about whether someone chooses Arial or Verdana or Times (just as long as it's not Comic ). But all of the fonts, at the standard Size 3, are too small for reading at length. It's not a big deal for newsfeed updates or blog comments or emails, but when it comes to reading poetry or fiction that's potentially hundreds or even thousands of words long, a larger size is much more comfortable to read for most folks. It's doesn't have to be giant, but an item in a Size 3.5 or Size 4 font is demonstrably easier to read than at item in Arial Size 3. All you have to do to change the font size of your item is to sandwich it between {size:X}{/size} WritingML tags, where X is a number between 1 and 5 (in increments of .5).

2. Line Space. The default line spacing on this site is 1.2. Increasing it to 1.4 or 1.6 can created so much-needed separation between the lines to create some white space and make it easier to read. You can create additional line space by using the {linespace:X}{/linespace} WritingML tags, where X is any number between 1 and 3 (in increments of .1).

3. Paragraph Breaks. When reading things online, the name of the game is contrast between white space and text. The more balance you have between the two, the easier it will be to read. Even though printed materials like books and magazines don't typically add a line of separation between paragraphs, it can be a really good idea for online items in order to increase readability. This one doesn't even need any fancy WritingML tags; you can just hit 'Enter' an extra time between paragraphs when formatting them here on the site.
