Do you expect Mojang to be a super fast cyborg that can add 2000 features in 50 minutes? The Mojang Team are just like us, human. They need a rest. Also do you know how much time they had to code? Can you run a company that can make good quality features within 2 minutes? Always remember, Quality is more important than Quantity.
In my opinion they aren't slow, they have just shifted their interest into making other games, they know they can't always stick with minecraft as their main source of income, they have to expand. You can't always milk the same cow.
Some people are just plain ungrateful. Complain about this, complain about that, complain about everything. "Minecraft is getting too few updates, it is boring now!" "Too many updates! Mods can't keep up! Way to ruin the game!" Really, just REALLY?!? If I was in charge of the forums I would remove all of these pointless and useless rant threads.
Look, Minecraft was first released about 3.5 years ago, and updates are still being released. None the less free updates. Try to find another game who's company has employees like DinnerBone who actually are part of the community and watch youtube videos about their game to make it better. Mojang isn't lazy, they are amazing.
They make a new snapshot every week, they do not add it to the game because of the bugs.
And also, they are not putting the updates in straight away is because plugins would be virtually impossible to use. After an update it takes a good 5 days or so to get all the plugins/moa up and running.
Imagine having to update your mod again as soon as you finished with the previous update. Would you like that? No. So orang is also taking that into consideration. For those who want the updates can go install the snapshot or use the curse client and load the game with the snapshots.
nothch mad loads of updatesbut not with very much content, he would squish a few bugs, try to eliminate lighting problems, make a funny thing for april fools and a new mob (rarely) ....in half a month that is. jens insead is slower each udate abot 3-6 months but he adds tons of things, the pretty scary update, with witches, the wither, wither skeletons, beacons, new items and texture. and dont forget 1.5thats coming that introduces things like the hopper, dropper,light sensors, comparators, minecarts with enough a lot of things (TNT,hopper, ect.) and a lot more....so you want a slow but very consistent update or a fast quick but not very consistant update??? some people say fast some slow, but i prefer jens slow and good updates, im not sayong notch isnt good, he was awesome to say the truth, he made mincraft and updated it for long. but if updates are quick and do not have a lot content its not very fun to update it and wait for the mod you loved is available for your version, but then when the mod is available guess what, another update....
Why can't you be happy that they are still updating it, what if one day they just shut it all down and you couldn't code it in or anything, everything was gone, then where would you be, take a light in knowing that they are doing things, a lot actually, snapshots are frequent, and frankly if you don't like it, do not take it out on Mojang, they have a lot of things to do, unless you know... You want to start your own game.
