Both on the forum and on my blog, I' say "These stories were first posted on ASSTR," without any blowback. If the implication is to go there instead, that's a problem; if the implication is that the other site has collapsed, nobody minds.
For a long time, there was an interesting beneficial cross-connection between the two sites. Most readers would start out on ASSTR, then would eventually discover SOL, and would occasionally bounce back and forth between the two. Many of us authors would even post to both, which only helped the process.
As has been noted, most readers come here for the porn, but after a while, they start looking for something meatier--either something more involved, longer or better written, and we have writers who fit both niches. The straight out stroke stories garner most of the attention, but between hand-workout sessions, they'd relax with a chapter or two of the more serious stories.
However, there's really never been another site which has ever fit that natural co-operative role with SOL, as most simply want to siphon readers away, rather than share readers to promote their own works too.
