Maybe I'm missing something obvious, but the reason that this feels like a combination of government-waste and possibly virtue-signaling is that only the column headings seem to be sign-translated. Even if it lets some people know that they click on the tourism or jobs or culture section of the website, the content within those pages doesn't seem to be sign-translated. So how does it really help anybody? Hell, can you even get to this website in the first place if you can't read?
And I don't know how Columbia's Internet works, but if you can read and aren't wealthy enough to afford fast Internet, maybe loading up videos while trying to browse the site makes the site slower and a worse experience for everybody.
Perhaps the sentiment behind this is noble, and as an experiment it sure is interesting, but I'm not convinced that it really helps as is yet. Maybe this is a foundation for something more interesting down the road, but we'll see.
PS: As a side note, while I can't read the content, the site itself looks pretty visually interesting and well-done.
