Blackboard Collaborate is the only program of this kind that I have used so far, therefore I cannot compare against other programs that are alike. But, I would say that I will be using this tool for a long time, because it offers me almost everything that I need as of right now.
Using Blackboard Collaborate is great especially when you have to go out of city for an important task and you can't attend a course class, but you want to be up-to-date with what happens. With blackboard, if used properly you can keep yourself up-to-date with everything and at any time that you want.
The reason for this rating is that the software is a pretty good tool that can be utilized for use in all of the Universities around the world. It has the capability to fulfill the needs of various different education systems. Although, there are slight improvements that are needed, therefore the rating is at 8.
The availability of the software is quite impressive. You can access it at any time that you want and from anywhere that you want, but that depends on how the software is set up by the University. There might be sudden outages due to not having enough space on your database, which we had that very issue happen recently here at our University. During that time, you could not access their blackboard at all until it was brought up online again.
The performance of the software is remarkable. The loading speed of the pages is more than satisfying, it all depends on the users internet package. So far, there wasn't any issue of Blackboard slowing down other software or systems when integrated with them.
