Slideshare is a rather popular 2.0 service which somehow manages to not attract a lot of attention. It’s a sort of under the radar service that everybody uses, but nobody hypes it. Maybe it’s because of the somewhat dull design or the fact that the founders don’t trash parties in the Valley (Oh wait, they do! See pic).

Anyhow, the service does have a large following – for instance, 1113 people have subscribed to their corporate blog. Moreover, everybody who wants to share a presentation online seems to embed it on Slideshare. That’s probably the reason why they raised $3 million in May this year.

So let’s give these folks some well-deserved attention. They’ve just released a new “more professional, clean, clutter-free” design. Part of the change is a focus on navigating the site. There’s a more visible search option, the categories are right in your face and the menu at the top is larger.

But most importantly, Slideshare has dropped the “beta”. Yes, the service has matured and isn’t in some informal test phase anymore. Under the radar, but oh so successful.
