Google built Hangouts into its services as a replacement for the Google Talk messaging service, but Hangouts adds voice and video calls. It's unique for this roundup in that it doesn't require an installer, it just works in your browser (though getting the Chrome Extension is recommended). It's perfect for talking to other people on Google—you can get up to nine people in a video chat, all for free.

Evernote has one use: be your online repository for everything. Scan it, shoot it, type it, whatever, just put it in Evernote to find later. Most text, even in pictures, is OCRed (optical character recognition) so it's searchable later. Organize the notes into Notebooks, then access it anywhere. Despite some ups and downs in its business model, it remains our Editors' Choice for note-taking on multiple platforms—even if for free you can only use two devices (plus the Web interface).
The thing with buying leads is that they likely come from a list put together of candidates that may or may not have an interest in similar businesses and services. These bought leads are not guarantees, and some of them might have interest in related products, but will not be suitable for your business. So when you work to convert these leads, you will have no such luck. But when you find a lead organically and work to convert them, you know they have found your business and they are actually interested because they sought you out, and not the other way around. This fact alone will bring you more luck in the conversion process.

Free software played a significant part in the development of the Internet, the World Wide Web and the infrastructure of dot-com companies.[58][59] Free software allows users to cooperate in enhancing and refining the programs they use; free software is a pure public good rather than a private good. Companies that contribute to free software increase commercial innovation.[60]
For reference, see OSI FAQ : "How is 'open source' related to 'free software'? The Open Source Initiative is a marketing program for free software. It's a pitch for 'free software' on solid pragmatic grounds rather than ideological tub-thumping. The winning substance has not changed, the losing attitude and symbolism have." Outside this rather unkind FAQ item, the OSI and its supporters have generally avoided the term "Free Software".
Something to always watch for: crapware installers. To make ends meet, many creators of otherwise great free software, or the services that offer the programs for download, bundle in things you don't want. Worse, the installation routine obfuscates the steps, so you provide the unwanted program tacit permission to be installed. For more about how to spot and avoid this problem, see How to Clean Crapware From a New PC, and check out the Uninstaller section of this very free software collection.

In the GNU project, we use copyleft to protect the four freedoms legally for everyone. We believe there are important reasons why it is better to use copyleft. However, noncopylefted free software is ethical too. See Categories of Free Software for a description of how “free software,” “copylefted software” and other categories of software relate to each other.
Everyt business runs on opportunity. It runs on the potential of the new prospects that could turn into paying customers. These incoming prospects are called sales leads and they hold a strong place in the success of a company. So today we ask whether or not buying sales leads is the right decision to help your company grow, or if free sales leads are the way to go. Let’s look into the basic terms before we dive into the whole ordeal:
Currently, many people use proprietary software that denies users these freedoms and benefits. If we make a copy and give it to a friend, if we try to figure out how the program works, if we put a copy on more than one of our own computers in our own home, we could be caught and fined or put in jail. That’s what’s in the fine print of the license agreement you accept when using proprietary software.
While most hard-copy business directories are located in the Reference section of the public library, you should still ask your Reference librarian which databases they carry and where to find them. If your local library doesn't have the directory you need, then place a request with the librarian because very often the librarian will be able to subscribe to the source you're looking for. Many libraries have computers set up so that patrons like you can go online if you prefer the electronic version. That said, not all of these databases have been converted to e-versions. 
Many people write their own license. This is frowned upon as writing a license that does what you want involves subtle issues. Too often the wording used is either ambiguous or people create conditions that conflict with each other. Writing a license that would hold up in court is even harder. Luckily, there are a number of licenses already written that probably do what you want.
