As you know, the official releases for OTB are hosted at sourceforge.net. Using the tools available on the site, we can track the number of downloads of the files.
I have used this tools and I have obtained what follows. Since October 31, the date when we released OTB 2.6, there have been 282 file downloads. Making a pessimist estimation, we can assume that every user downloads 3 files (the library, the applications and the Software Guide). This leads to 94 downloads in 2 weeks.
I think this is not bad at all, and shows that the OTB users community has reached an important critical mass.
Let’s keep the project moving and improving with the help of everybody!
