is it correct?

[Greg]

I would do it like this:

"Thanks for your Follow Friday, I don't update my Twitter account too much, though."

[I Am Denmark]

No.

Correct version:
"Thank you for your Follow Friday, I don't update too much, so my Twitter account, though."

[Terry]

May I suggest?
"for your fallow up last friday, although I don't update my twitter account much now."
Sorry I am a bit conffused as to what you mean by follow friday?

[Cookie monster]

I would say
"Thanks for your follow on Friday, though I don't update my Twitter very often"

[Jeffrey]

i'd say "Thanks for the follow on Friday, I don't usually update my twitter much"

*note
if you put don't after usually it means something totally different just saying make it simple
