I create my My blog/fashion deal site (http://mutex.me) around 2 months ago and got off at a very good start using mainly forums for promotion. Got to around 2500 visits a day from 1000 uniques. But now I'm stuck. The visits are just hovering between 2500-3000 per day and no matter what I do its not increasing anymore.

Does anyone have any tips on how to further promote the site? I've tried most of the usual tips (SEO, joining directories, social networking, forum posts).

Right now I'm thinking of doing guest posts or giveaways as a way to increase traffic, but not sure how effective they are. Does anyone have any experience with these?

Thanks!
