I hope this one seems more polite and palatable to you.

Anyone who could reasonably analyze your algorithm, whatever
it may be, is already intimately aware of sieveing.

Half the time, I'm not sure what MY motives are for doing things,

This is certainly true. However, I don't see where he claimed
that he had nothing to learn. However, anyone who is serious
about prime testing/hunting in the large numbers searched by
GIMPS knows everything necessary about sieveing. It isn't even
possible to represent the sieve in a computer in these ranges.
Hence, the lack of interest.

It can't be fast if it can't be run at all, which, I think,
is the point. The subject matter here is GIMPS. Since a
sieve just isn't feasible in the range GIMPS is exploring,
a sieve is actually pretty much off topic. THAT is the
reason for lack of interest. It isn't that what you have
might not be interesting elsewhere, it just isn't a matter
of interest to GIMPS afficionados.[*]
I don't mean "of no interest at all", but I mean "when
posting here". It's possible that there are many afficionados
who would be interested in a variety of topics. I, for example,
repair and restore to operation vintage tube (valve) radios.
I participate in a couple of mail echoes which are devoted
to these subjects. I do not, however, wish to see posts about
those topics in this echo.
If you got really interested in knitting by hand, and found a way
to speed up knitting by hand twofold or threefold over the
usual ways, and posted a message about it on an appropriate
forum, you'd probably generate a lot of interest. If you posted
it here, you'd find a lack of interest. Not because your
discovery was not noteworthy, but because the people who
collect here have a common interest in large primes,
not knitting, though you might find one or two who have
some interest in it.
Likewise, since a sieve is an inappropriate method for searching
for large primes, you find a corresponding lack of interest.
That is not a comment on the noteworthiness of your discovery,
but rather on its topicality in this mail echo. It's not much
more on topic than a post about hand knitting.
If you can find a list, echo, newsgroup, or web forum which
has as its topic of interest speeding up algorithms for finding
small primes, or just algorithmic analysis, or something like
that, and posted there, you would likely find more interest.
In the meantime, it seems to me that you are simply posting
off topic. The moderator will make any decisions, of course.
[*] Now, if you found a way to represent a sieve on a computer
which would work in the ranges GIMPS explores, that WOULD be
ground breaking news interesting to people here, simply because
no one has ever figured out how to do such a thing. However,
that doesn't seem to be what you claim. The interest might
be somewhat fading, however, unless the speed could also
compete with currently used techniques, which seems unlikely.

You have found the bank of Larn.
I can explain it for you, but I can't understand it for you.
I speak only for myself, and I am unanimous in that!
