Andy,
Nutrients are prevalent in Ales and other AG brews so added nutrient not required. In some wines and certainly in Cider which are low in nutrients then a teaspoon full helps the fermentation establish and work well.

I know Kev has started using it with his AG brews, and seems to like the results. Hopefully he'll be along soon to provide some more details...
My fermentations seem to run out of steam a bit, and I'm wondering if nutrients might help. For example, my current brew started well (short lag), and then went from 1044 to 1015 in 3 days. Since then 2 days have passed and it has only dropped to 1014. I'd like it to get close to 1010, so I might give nutrients a go (of course there may be other reasons for the fermentation behaving this way)

I dunno mate, I'd try eliminating other causes for a high FG first. Servomyces is quite expensive - if you're using dried yeast I think it might be cheaper to use 2 packs than add yeast nutrient!
Have you looked into the other reasons? High mash temp, low fermentation temp, under pitching...? If you crack the problem that way you'll have improved your process without needing to spend on nutrient for every brew.
Sometimes it may be necessary to use yeast nutrients if you are using a yeast strain that is fussy such as a Saison or in high gravity beers so they have all the nutrients they need to build cell walls to protect them from the higher alcohol content. But for standard ales it really isn't necessary and if you are having problems it's best to check the other factors as stated in the previous reply. I also make sure to have a high cell count by doing a yeast starter or by pitching multiple vials/sachets.
