Entering the massively crowded free classified services comes PostAClassified.com, which offers pretty much the same as the army of its competitors: free classifieds space and free ad browsing; the scope and variety of categories has nothing to envy to its competitors, as you can use it to search for anything from a job to investment/business partners, used cars, rental properties or any other thing you might be up to, including adult services and personals.
You find other things too, namely an impossible amount of ads: tons and tons of contextual ads, which are not only a nuisance, but will soon be obsolete as a business model, as most modern browsers allow users to block out ads completely. On the good side, though, note that posting an ad is as easy as you could wish for: you need to choose the state and city you want it to appear in, attach a picture of up to 900 KB, pick a category, a title and enter a 255-character description; you can also provide an email address to receive answers, or a URL pointing to your site. This will make your ad appear in the site instantly and remain there for a day; you’ll get an activation link in your email, and if you confirm the ad it will be posted for a whole month free of charge.
