I encourage algae growth as much as possible. I keep it cleaned off the viewing panes of my tanks, and when it comes to stuff like hair algae, I pull it out by the handful and usually use it as food in other tanks, but even then I am not trying to eliminate it, just control it. I appreciate its beneficial effects on water quality, and I generally like the soft natural look it creates.
If you like the type of tank where every surface is spotlessly clean and looks like an operating room...you won't like that kind of growth.
The one thing of which you need to remain aware is the health of the stuff. If you suddenly cut off the lighting to that tank, or if the algae is allowed to grow so thick that the bottom layers are deprived of light and begin to die, then the whole tank can become very foul almost overnight. So maintain control of the algae, don't let it choke itself out, harvest or thin it out freely (like any other plant) and enjoy a natural tank.
I should mention that my tanks all have very thin substrate, or often none at all...so for me, there is no concern with anaerobic pockets beneath the surface. I'm assuming that could be a problem if you have a thick substrate bed that remains undisturbed for long periods of time.
