I'm on Hitched a lot less these days and I'm not planning to use the new site. TBH I think I've just gone off using the internet in this way- if I read a post I heartily disagree with these days my first instinct is no longer to argue against it but to think "why am I wasting my time reading this rubbish?" and log off- I think I've just spent too long here, really. In addition, I don't find Hitched as funny or as fun now certain regulars have left (although plenty of fun, funny people still use the site, of course).
I haven't experienced the slowness, other than once or twice, and I'm not too bothered about the swearing rules either way- I can see why Darren doesn't want a board full of four-letter words and it's hard to draft a rule that distinguishes between carefully crafted sweary bon mots and offensive rubbish, so I suppose it has to be one rule for all.
I think I've just gone off forums though- it's not a Hitched thing.
