Well, I can't speak for a year as it's only been about 9 to 10 months (depending on if you want to date it from the first half or the second). The best I can answer is yes and no, which may be more confusing than helpful but....
The coraline has continued to spread and cover portions of rock that were bare when I received it (most of the rock is now pink with some more light protected areas a deep magenta). My macro algae is all but gone from the tank after having a veritable forest of several variaties of calurpula (you guessed it, went sexual in several waves and eventually didn't come back). I had some halimeda also but the clean-up crew mowed that down (amazing given it's structure) after the calurpula was gone. Same with some red gracillaria like algae.
Sponges have been a mixed bag. I have several green and pink sponges that have slowly enlarged. I had several grey sponges as well as some orange encrusting that disappeared from the tops of the rocks but have held on in more light protected areas. There is a yellow finger sponge that has waxed and wained that appears to be growing again. There are a number of sponges that were a beautiful baby blue when I received them that have faded to creamy color with just a hint of blue, yet they seem to grow and enlarge.
The corals were pretty much brown from the get go and those that were exposed to a lot of light (closer to the surface in my arrangement) don't seem to have faired well. At the same time, I had a brownish rose coral that was about the size of a dime that is now the size of a 50 cent piece and flourescent green.
I hope this doesn't sound too negative, as I really like the tank and the way that it has matured for the most part. If I had to do it again (knowing what I know now), I would have placed some rocks with sponges in a more shaded position and the same with some of the non-photosynthetic corals. I also would have reduced the number of snails and hermits a little earlier in the process as they quickly over whelmed the algae.
Over all, my nine month old tank looks like several 3 to 4 year old tanks I've seen that were started with non-TBS rock (sans the coral collections they might have

). Given that this is my first try at a tank of any kind, I think it's pretty good
