Update on social sites icons on the site – youtube subscriptions + friends request on facebook – SOCIAL SITES

Since I added the youtube/facebook and twitter icons to the site there is still VERY LITTLE change on subscribers or friends requests.

A couple of friends requests in this week and close to no change on the youtube subscriptions side with around 4 subscribers/day for the last 2 weeks.
The reason to keep them on the site is obviously not to massively increase numbers but simply to ad familiarity and connectivity for those who visit the site.
Is it actually worth it having them there?
Keep them or take them away?
