Well, except from on your own blog, which is of course the best as you have complete freedom, there are some other social writers sites that I enjoy too. It does depend on what you are looking for and why you want to write, but the three sites I am going to mention below cover a broad range of reasons.
What are these reasons? Well, most people write online because:
A) They love writing.
B) They want people to read their writing.
C) They want to earn from their writing.
D) They want to promote other sites (normally their own websites).
Hence, the sites that I have picked for you guys cover all of these conditions. These sites allow a link (at least) from your profile to your main website. Two of them allow signatures or text links in articles. All of them can make you money online if you build up a following and write frequently. So, without further-ado, here are my suggestions (you can just click the blue link to join):
1) Bubblews (High ranking site, with MASSIVE earning potential, easy to get readers and to get established in just a week or two. But, no links allowed that are self serving)
2) Hubpages (High ranking site, very social and can provide stable traffic/earnings. This site allows you to link to your websites in articles, but not to affiliates. The links are PR3. However, it will take a while to get established and traffic … maybe 3-9 months).
3) Infobarrel (This site is great for affiliate marketers apparently. They are quite strict on content, but allow links in signatures and multiple signatures for more that one site).
Obviously, read the rules before you start to write. But, if you follow them, these sites are pretty amazing!!
