Well done OD! I raise my hat for you, you are a real entrepreneur and you could make a lot of money by commercialising your idea as stated by Google!
In just eight months he has reportedly gained 18,000 followers, including in Britain, America and India, and caught the eye of staff at Google, which wants to find ways to commercialise his idea.
From my point of view, I'm very worried that this commercialisation is going to have an even bigger negative impact on visitors like me who don't use these Apps/BBM's to find sightings. The report of the impala is great, but is such a report worth 20 roadblocks caused by these groups, because I think for every one report like that, you will have 20 or 100 reports on where to find the Big5!
