The editors actually edit instead of sending silly edit requests; the people are so friendly and happy to talk with you; payroll is regular and bi-weekly; direct deposit, so no need to mess with PayPal and its fees and transfer times; excellent pay on most articles; and easy writer interface to work with.
Cons
Some articles are lower paying; there are sometimes lulls in available work; payroll issues are slow to be resolved at times; and you cannot select your own topics, they assign them to you.
