Look there for the suggestion named "Taming Animals". And just to point, i'm not angry, just a little pissed off. It's the 3rd time that i find one of my suggestions claimed by others. Sorry for being rude.
If you look at the
Player Tracked Suggestion List, taming of animals was suggested as far back as February 2010. It's not unlikely it was suggested before that, and not unlikely that it's been suggested 15 times since. It's not a matter of "people stealing your ideas", but rather the fact that some ideas will appear every couple of months, either because they're good suggestions, or because there are only a limited number of solutions to some things, so similar ones will crop up.
Each time such a thing is suggested, there'll normally be a slightly different take on it, or it's as part of a different overall suggestion - for example, the one in this thread is a sub-point amongst a suggested overhaul of all followers. Ultimately, if something's a good idea, slight variations are going to be suggested every few months. Each time it may be slightly different. Eventually, one of the devs may conclude an ideal solution from all the similar suggestions, and it may get implemented.
I would think it would be far more beneficial to say "I had a similar idea here, what do you think of doing it this way?" and then to discuss the relative merits of such ideas, rather than getting pissed off about who has 'stolen' whose ideas.
