I have been using Sulekha on and off for few years. Its a good site compared to many other sites out there. Only problem with this site is poor navigation. You will be easily lost. Some of the links are broken, these guys never fix it!
Contents are original, not displayed from other sites like glogblog does. There is a coffehouse where you can discuss stuff. There are many city pages. There are Events pages. Sulekha has many features, I dont use all of them. Some of the features are plain waste anyway.
Whatever features I use, I am happy with it. If you post something in the coffeehouse on Monday morning, you would find atleast 2 responses by Monday evening. You post something on sunday, usually there will be no responses until Monday! I think many people read it at work.
Problem with this site is just too many ads. Wherever you turn, you will be swamped with ads. Its really irritating. If you can tolerate all those ads, this is a really good site.
