Having lots of publishers is both good and bad news for an inexperienced writer. With a number of publishers, it can sometimes be difficult to find the most reputable publishers, but the added value is that writers can get the best deals for them.
Just because online publishing is a much easier business, it doesn't mean you can write junk and it's accepted. If the process was easier for you now, it's easier for everyone.
This means that there will be many ambitious writers who are competing to grab the attention of readers. Hence, you have to work really hard on quality to attract readers and make them loyal to you.
You need to realize that "online publishing is a written compromise."
In short, if you are a difficult writer and don't want to waste time and money looking for a literary publisher or agency, then online publishing is a must.
