considering the rate of posting there (1 a week or less is not a lot) compared the rate stories are posted here, it's here that the good stories are getting "buried under junk".
Sorry, I didn't mean that the stories themselves are junk, after all, most are considered classic best-selling sci-fi novels. Instead I consider them to be freeware junk (stories loaded at no cost) to the site but which overwhelm the contributions of new authors struggling to find their voice.
However, comparing the site to SOL, I can easily find my own stories when I post on SOL, whereas I typically have to search through multiple listings before finding my stories when they post on sci-fi. I don't know how many new chapters are posted on scifi vs SOL, but anecdotally, it doesn't seem compatible.
