It's a fair cop. Things have been a bit uneven of late. And in the old cliche words to all not just the asker, "It's not you it's me."
Typically, I like to get a response out within 24 hours. Actually, I like to have one out within 2-4 hours. So what goes wrong?
For starters... best way to question me is via IM with an emphasis on AIM. I am horrible at phone conversations. But let's focus on email.
If you don't get a response from me within 24 hours there are a couple of possibilties.
1) I didn't think the question necessitated a response. (Sometimes a vastly wrong assumption on my part)
(the writer of this wrote me a day or so back and didn't know if the mail wanted a response)
2) I thought through a lengthy response and then did not have the time to get it together... (this is often followed by:)
3) I got it in my head that I did respond and actually forgot to.
4) Life got insane (boy, work, etc) and I need to get back to it.
For the Andrei can be a slightly absent minded person and thus IM is the best way to catch him directly in the moment.
Please note.... if you haven't heard from me... It is VERY UNLIKELY that I did NOT get your email. I no longer trust automated spam filters and have written my own.
So... if You are pending a response from me... after about 6-12 hours if it is time critical... please feel free to ping me. If you send me a ping "Hey, did you get my email"... those I typically will get to as soon as I see them to give a brief overview of why there hasn't been a delay. (Thus what we call a pong to the ping)
Believe it or not... when checking if someone is online or available... I may just IM them "PING." Most of these people know to respond with Pong.
So... hopefully this helps not merely the asker but the rest of the readers.
And I'll also take that to mean that the email wanted a response which will occur right after this post :-D
