No I didn't like this service at all. First things first, some of the templates are of poor quality, really poor one and even if they have many views and downlaods, they are still poor. It's not cool. Secondly, the free access is proclaimed for 30 days but it's not like that, The website intentionally cheats on the customers saying that its for free for 30 days. MB the diversity of various things are cool at Scribd, but in fact it's the service that is barely worth your attention. I don't recommend.

Wow, this is a full-fledged library of super valuable materials for people from various sphere of our life! I found them casually when I tried to google solution for my marketing camapign, and then there was a pop-up ad that redirected me here. It was interesting for me to find out how to boost SEO performance, what are contemporary instruments used for that and some other curcial information. Now I am a regular here, because I every week find materials and research them. Thanks a lot, guys, you are doing a great job!

it was a good public forum for sharing knowledge without greed. and nobody is even visiting the Scribd site, but when they bought Slideshare they screwed all the people's effort and vision who uploaded their slides free of cost as contribution. after such acts, Scribd might never see success.

As many of the reviews indicate, this can be a useful site for presentations on many subjects. However, there are also short "shows" that do not discuss the book or subject in question, but link to another download site of dubious safety—a kind of "bait and switch" deception. See, e.g., Ley and Bonestell, _The Conquest of Space_.

SlideShare is the world's largest community for sharing presentations. With 50 million monthly visitors and 90 million pageviews, it is amongst the most visited 250 websites in the world. Besides presentations, SlideShare also supports documents, PDFs, videos and webinars.
