ghost - a webtop with big ideas, see others…Qnext and others are webtop file sharing

linebuzz - inline comments for your blog, that is a visitor can highlight text and leave comments refering to that text in particular. Others can hover over the text and the inline comments will pop up (you can also reply), the inline comments will also be displayed in the sidebar.
Need to be registered to leave comments, and a user has a space to keep an archive of all their inline commenting…check out their blog to see it in action. If it’s just a regular comment module you are after see JS-kit and others. [via PB]

heeii - a suggestion/recommendation site in the vein of Reko, Stumble Upon, blogrovr…The Coop and others are more a link sharing network. [via m]

50 matches - a meta-search engine for the human indexed web, well at least the social bookmarks/memedigging portion of the web…see others at my post on theagoo.

Hypeit - formerly Spokeo (a social network RSS Reader). I still see this as a social network RSS Reader, basically you:
1. add your feeds, if you can’t remember the feeds from all the services you belong to, use the form where you can choose from a multitude of services for easy adding.
2. to add friends do the same
- a friend can be a their blog feed, their YouTube feed, etc…
- a friend can also be a person’s account in hypeit, so when you click on a hypeit person you basically see their subscriptions

What they have changed is that you can comment on a story and hype (vote) a story, when you do this, that story will appear on your friends accounts. So it doubles up as a link recommendation social network like Heeii above and others.
