Though increasingly fewer people use this struggling Office Suite, Apache OpenOffice is reporting 40 Million downloads, since the release of 3.4.0. This is is a good sign for Apache's office suite, but not necessarily a good sign in any other way. Why? Well, if so many people are still using this Office suite (and so many downloads suggests to me that many of them are new users), then it means that too few people are aware of the better alternative - LibreOffice.
Now, don't get me wrong, Apache OpenOffice is Open Source software, and its existence is quite okay, but it's lagging behind the competition in a serious way, and its unlikely for things to change very soon in the near future. One area where it does stand to gain is in the inclusion of IBM's Lotus Symphony code, which is said to be a coming addition in the not so far future. It would bring a new user interface to OpenOffice that could seriously give LibreOffice a run for its money, so to speak.
Other than that however, Apache OpenOffice does not nearly stand a chance, and if you still use it, take my advice - move on.
