I'm not sure actually. I have also noticed lately that I am not getting notified with replies at all in the last few days.
Basically all I do know is refresh the 'replies' tab on my profile every few minutes to see who has replied. Hope that helps :)
PS. If I achieve 5 resteems on this post, I will reveal what I think are the best investments to achieve higher yields (Like everyone is asking LOL).
I am not sure if you cover index funds as 401k options over managed funds by major investment companies. The lesser expense ratio of index funds can earn you an extra 1% a year. Within the options that one's employer provides, there are always market mirroring index funds one can move into instead of the ones they automatically put you in.
Index funds are actually one of the things I haven't put too much of my attention to. I don't even consider them simply because there are more than enough very promising, strong investments out there nowadays.. I don't want to overwhelm myself if that makes sense :)
you should look into putting at least a small % into index funds -- it's seriously free money, at least here in the USA. Also look into www.wealthfront.com
