Some suggestions:
- Quality selfshot-style photos of models, for their profiles and for promo.
- Model profiles to be well written by a native English speaker, even if it means making shit up. (Half of Webcams.com models have "hot fantasies / no fantasies" as their default turn-ons and turn-offs)
- Uppers for models who need them
- For Russian and Eastern European models, tap into the internet's fascination with Russia and Russian women. Get her to make a video on a dashcam. Have fun in the snow, then do nature pics in summer. (Some of them do but it's nowhere near good enough)
- High quality cameras as has been suggested.
- Attention paid to how the top American cam girls promote themselves on social networks. Yes affiliates can do this, but it's not much good if the end product is so disappointing.
- Blur the distinction between network and indie cam girls. Have wishlists, clip stores etc. that surfers can buy from and affiliates can still get credit for.
I personally think that the best webcam site hasn't been invented yet. MFC, Chaturbate and the new free one all have their flaws. Livejasmin's new design looks like a step in the right direction though.
