Good suggestions. What would you say to someone that is generally not interested in blogging or speaking?
I think the question re-phrased might be "How do I show others and the broader community what value I can bring without speaking or blogging?"
You can build a reputation among those you've directly worked with. You might have solved some tough problems in the companies you worked for.
The occassional post on LinkedIn, twitter, etc. just stating some result you achieved can help too ("Our team just built this really awesome thing X").
If you don't want to get involved on social media, you can still get involved in the local community (just attending user groups but not speaking, etc.)
Taking on the big, difficult projects at work.
Find a need in the dev community and build a tool to help?
In the end, I guess you get out what you put in?
I can get with that. I ask because it seems like we're always telling juniors "You need to blog and speak as often as you can to have a career in software development", which may not be a good fit for everyone. I spoke at RailsConf a couple of times; rarely go to meetups and my LinkedIn blows up all the time. At some point, IMHO, it's more valuable to be excellent at your job than to be excellent talking about your job.
I'm not trying be that contrarian "ackshully..." brogrammer. I'm simply saying for those of us who view social media as The Black Plague 2.0, there are opportunities for us to shine (as you have shown above, so thanks for that).
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
