Amberlim, In my case, Hubpages is the very first online site
on which I began to publish. Prior to this, I had written a monthly column for a local magazine, as well as doing a great deal of private work in proof-reading, editing, with a few dozen magazine articles scattered here and there.
I do not write with the goal of "earning" loads of cash. I'm happily and busily involved in many projects as a single retiree. I use some of my personal free time to write here for the sheer pleasure, education and social aspect.
Here 5 years now, I feel very much a part of an incredibly wonderful & varied community of some of the best amateur and professional writers anywhere.
If, as you mention, there are "other similar & possibly better platforms" than HP, I am not aware of them. In fact, it's seems to be common knowledge that many who have gone elsewhere, admit to being disappointed and quite often come back to HP.
I have built several close bonds with fellow writers who I now am proud and pleased to call my "Friends." Just as with anything there are the positive and negative issues, but nothing thus far has been so unbearable to cause me to voluntarily cease all involvement here. It takes a whole lot of repeated disillusionment to prompt me to QUIT anything.
Once I have committed to something or someone, I'm by nature a loyal and dedicated individual. Good question! Peace, Paula
