The answer to use free software is not so simple. It can range from a yes to maybe to no. But let us start by being positive.
Yes, free software can be good. In fact they can be very good. I use a small program with Photoshop when I work with Photographs. This small program is hardly
2MB and yet it is so versatile that I use it on a daily basis.
I use another free program to do stitching. Though easy to use and excellent, your end result is just slightly blurry. Good enough for me, but not good enough when you want to sell your product.
Then I discovered an excellent, free piece of software. What it does is making life easier for you if you are running an Affiliate Program under you. Get Into PC Instead of letting your Affiliates struggle it out, this little program gives you a few options. When you fill in your detail are delivered with a finished product. A webpage, which your Affiliates can download. All they have to do is fill in their own code and submit the various material to wherever they want to. This includes the HTML, Banners Text Links, Banners, Pop ups, E -mail campaigns and a few more things. Is that cool or what?
Maybe others are not so good. You get a small free program that takes your article and then changes the wording so you sit with a brand new article. The snag is that it does it in such a way that your article is unreadable. The changed words do not fit the sentence. It is not good English and you spend more time correcting this than you would starting an article from scratch. Some do just enough that you need to use a second program to finish the job. In design work this is very convenient but in text work this is not good enough.
Lastly we have a very strong No! For various reasons some free software are so bad that all they do is slowing down your computer. You spend hours trying to find your file and then it is in a file type your programs do not want to open. You spent all the hours working on the project just to find out the limitations leave you cripple.
