After a brief foray to another story site, which shall remain nameless but starts with 'L', I've come to the conclusion Gromet isn't all that bad despite a few things I find irritating as an author. As an experiment I posted a few, old stories at that other site. Out of four submitted, three were accepted ('Whispers in the Ear' was somehow regarded as being primarily about murder, no idea why). There were some good points but one seriously bad one.
First the good points, and ones I miss on Gromet. There is a view counter for the number of times the story page is opened. The old BdsmLibrary site also had this feature. Reality is virtually no one posts feedback on the stories. At least with a view counter (and discounting about 10% for search engines and site scraping bots) this is a way to evaluate the story's reception. It's not ideal; there's a misplaced temptation to compare counters with other stories, but that doesn't take into account the length of time a story has been available. And it doesn't indicate how many actually read the story, rather than moving on after the first paragraph (TL;DNR, too long; did not read), or what percentage were returns from the same reader.
The other site also has a rating system, averaged over the number of readers who post a rating (again, similar to the BdsmLibrary site). Nice but doesn't always reflect true opinions. Don't like the author? Mark every story with one star. Along with ratings there's a 'Like' counter but no "Dislike", which I think is a good idea since it filters out the problems with ratings.
By the way, I found the view counter increment rate falls off a cliff after about a week. At the same time the rating average went up, what we mathematicians like to call 'inversely proportional'. I attribute that to fewer but more discerning readers.
The one serious problem? It's the subject matter of many of the stories, which overflows into the forum and chat room. Gromet has excellent policies in this regard. That other place? My first impression was 'a sewer'. It went downhill from there. I lasted about ten days before pulling all the stories and heading for the nearest exit. Ironically, almost anything goes for story content except for somewhat arbitrary restrictions (very odd given what is accepted) which would ban most of my stories.
My complaints about the Gromet format? The first one is the way longer stories are posted compared to a series of related but independent stories. Sequels are not additional chapters in some kind of serial format, but that's how it comes out looking at a summary of an author's catalog. Sure, long stories can have separate pages, but the links should be off the first story page, not a chapter list on the site home page. Keep the home site and author story lists uncluttered, with only one entry per story. Looking at my own listings, how do I tell the difference between chapters in a novel, as opposed to a series of related (by location or characters) but primarily standalone short stories? Now when it comes to the serialized story, one chapter a week for example, I can see where there has to be a way to know if the latest installment is available, in which case post first and most recent chapters as separate links in the home page, with the first page used as the table of contents links. I never use the serial format (personal opinion: installments are either a sign there's no coherent plot or it's a cheap trick to gather eyeballs, but that's just me).
The other complaint? Add page counters, give us some way to measure feedback. Writing a story takes considerable effort; it would be nice to know more than two people read it.
One line summary: the grass is greener on this side of the hill. The other side is full of loco weed (Jimson weed for those outside the central U.S., a nasty hallucinogenic for cattle and the occasional idiot who tries it out).
