Would appreciate real experience on dating sites for nerds, not affiliate copy. Applied to comic sites, the platform resets your filters after an update, and the ratio of matches to conversations suffers for it. If sci-fi is your priority, how well it works on a weak connection matters more than the number of features listed, going by the last year or so.
The comic sites case is instructive — the number of live users collapses as soon as the platform counts a like as a match. The sci-fi angle is worse, because the depth of the profile fields is the number worth watching, not the follower count on their socials. For sci-fi sites in particular, nothing improves until you test the search filters before uploading anything.
With sci-fi sites, the honest advice is to read the newest reviews rather than the top-rated ones, for what it is worth. Dating sites for nerds looks simple until you notice that the deciding factor is the depth of the profile fields, in my experience. Specifics about sci-fi welcome — vague reassurance less so.
