Hi there,

Someone commented that on my new Code-Maven LinkedIn Page there isn't enough Perl. So I tried to look around. The #Perl has 360 followers. Golang has 3,603 followers, and Python has, no I don't even want to write it down. (COBOL has more followers on LinkedIn than Perl!). So one thing you can do is to follow #perl on LinkedIn.

There are also a number of Perl-related groups. Far the biggest is Perl Mongers with 8,283 members and then Perl Developers with 3,122 members. So apparently the vast majority of the people who are in these groups are not following the #Perl tag. Interesting.

Another thing that you could do is to post your Perl-related articles in one of the Perl-related groups and also tag them with #perl. It might not bring in more readers, but it won't hurt. I guess.

Digging in history I found an 8-year or post of mine Perl developers and LinkedIN and apparently I had a post titled Business readiness of programming languages in November 2004 posted on

Enjoy your week!

like this: '***************pqrs'. See also comments on Reddit including a very good point, that you probably should not store Credit Card numbers. You can probably store the last 4 digits and then show that only.
