Duotrope, which lists markets and stats, is finally moving to a subscription service. Considering how long they've been running it at a loss I don't blame them, though it's a still a shame. There's a lot of people asking why they haven't tried running ads or charging markets to appear; I'm not keen on the latter, but I'm surprised they didn't try the former.
When it says most services are going paid early, I think they mean all - I certainly can't see how the site would have much functionality for someone who hasn't paid. It's going to lose a lot of users, which could affect the stats.
I'm up in the air at the moment. It's not like it offers me anything I couldn't do myself, though it is more convenient. It's been a while since I've found any new markets that have been of much use to me (compared with markets I've previously submitted to) but I still use it to keep track of deadlines and anthology calls. So, yeah. I've always preferred duotrope to most of the other market listing sites, and it's not like it's that expensive, but I just don't know if it's a service I use enough to make it worth paying for regularly.
(thanks to the mods for the forum move - I wasn't sure it was important enough for BB&BC so I played it safe )
