It’s been almost a month since we last served up Platform Five, our (usually) weekly round up of the latest and greatest social media tools and Web apps.

To make up for the silence, we’re going to reveal some of the best places on the Web to find the tools that will make you the social media “go-to guy” of your business.

1. WebAppStorm.net. The most thorough Web app review site on the web. Add this one to your RSS reader now.

2. ProductiveWebApps.com. Daily updates of new tools and apps that will make you more productive and efficient.

3. MakeUseOf.com. The daily “cool sites and web apps” column gives you the latest and greatest tools being launched around the Web.

4. AppAppeal.com. More than 2,700 Web apps tested and reviewed for your browsing pleasure.

5. JustTweetIt.com. An endless directory of tools to enrich your Twitter experience.

We’ll try not to miss any editions of Platform Five again, but if we do, these are some of the sites you can call on to get your social media tools and Web apps fix.

On the Paratus Communications blog, PR Daily Europe contributing editor Adam Vincenzini rounds up five of the most-talked-about social media platforms each week. The feature is called Platform Five. Adam has agreed to simulcast it on PR Daily.
