I would estimate 10 - 20%... - JA Castillo

Maybe 50%? I have 50 subscriptions, and I do seem to look at a couple dozen of them regularly. - Kamilah Gill

Just guessing, I would say about 50%, too, but it's difficult to figure out since a lot of people are not as active on FF as others. - Trish R

I would guess 20 to 25% maybe. - Michelle Martinez

2% or less Everybody is sleeping when I awake and on the computer - Earl E Morningwood via fftogo

Less than 10%, I think. - Yolanda

I have a small group, so I would guess a good amount. I try to look at and evaluate everything they put up - RAPatton

It depends on what you mean by "interact with," but there's a small group, maybe 5%, who regularly like and comment on my feed and I do the same for them. - Michael Hocter

Between 10% and 20% perhaps. - Roberto Bonini

30% - clarke thomas

Around 5% or less for me. Which is good enough, I'd say. - Alex Scoble CISSP

Sorry. That's math. - Nine

5-10 % - Charlie Anzman

By interact, do you mean more than just reading their feed or liking particular postings? That at about 90%. If you mean something deeper like commenting and debating issues back and forth, it's about 5% - Neill Adamson

Neill, I meant reading their feed and comments (either on their posts or yours) and liking their posts and occasionally commenting. - Trish R

50% at best, I'm not terribly organised. - Mo Kargas

I usually read my main feed that has everyone I follow in. I read comments about articles that interest me, skimming past those that don't. Things that interest or motivate me more in some way, I will 'like' and those that interest me a little more still get a comment if I feel one is needed, or I have a strong opinion on the subject matter. - Ian May

Maybe 10% at best. - Mark Wilson

Probably about 10%. - Alexander Carlill

Same 10% or maybe even less here. - Svetlana Gladkova

I'd say 5% - AJ Batac

NFC, I interact with whoever interacts with me. I think a lot of my followers are not active so the percentage is probably quite small. - ♫ Rahsheen ™ ★

Same answer as Rahsheen - I have more than 500 followers and subscribers, and I doubt I see more than 100 of them on a weekly basis. - Tad, TV's Patrick Duffy

About 10%, much much less on a bad week. - Steve Spalding

I'm pretty active with most of my subscriptions, but the fact that the total number is pretty low helps me out quite a bit. I would say probably 75% - Aaron Krug

Coincidentally, I just wrote a little app to help figure that out.Or at least one particular slice of it. :) http://is.gd/3l3I - felix

Probably 15-20% - though many are inactive themselves. - Mike Sansone

0-5% because I am just too irregular with my interactions. IOW, I'm hardly on here at all during the day, so that limits my interactivity. - Pete Delucchi

5-10% - Nicholas Kreidberg
