Online collaboration between schools, teachers, and students has become increasingly apparent as our everyday routines become more and more connected via the internet. Of course, there are paid solutions that satisfy this need through Learning Management Systems, such as Blackboard Academic Suite, which frankly isn’t very good at all in my opinion. I can’t even count the number of times both teachers and students have complained about paid services that their respective institutions utilize.

Microsoft Office may be the most popular office productivity suite currently on the market, but don’t expect this to last forever considering the slew of new, web-based, and open-source alternatives coming every day. Recently, in only the last 2 to 3 years, not only has the number of MS Office competitors grown significantly, but also the quality of these products has increased immeasurably.
The best part about these new office alternatives is that they are completely FREE and they work with Microsoft Office, so if you or your company are locked into Office currently, you can integrate open-source software into your systems slowly and carefully. If you’re a consumer, you can now create documents, spreadsheets, and presentations on the fly, access them from anywhere, and open them in MS Office for compatibility purposes.
