The Google gadget is back and running
It seems Google has finally gotten around to fixing its Blogs I Follow gadget! The original issue was that it had completely stopped updating. You can read my previous post to see the workaround I used while waiting for the folks at Google to address the problem.
Below is the code I used to bring back the official Blogs I Follow gadget while hiding the temporary HTML/JavaScript fix.
To keep things organized, I saved both code snippets in OpenOffice. That way, if Google's gadget ever breaks again, it’s a quick copy and paste to deploy the temporary fix, and another simple copy and paste to switch back once it's resolved.
Note: The only change you will need to make is replacing my followed blog URLs with your own. I detailed step-by-step instructions on how to do this in the post linked above. Also you do this at your own risk.

The ARDC wants you
Applications are open Sept. 15 – Oct. 30, 2026.
ARDC is now accepting applications for our 2027 volunteer cohort. We’re looking for qualified individuals to contribute their time and expertise across several committees and teams:
- Grants Advisory Committee (GAC) – reviews grant applications.
- Technical Advisory Committee (TAC) – works on 44Net-related projects and policies.
- Grants Evaluation Team (GET) – evaluates and analyzes grant reports.
- Grants Communications Team (GCT) – writes about grant results for the public to learn from.
- Conduct Review Committee (CRC) – helps to evaluate Code of Conduct incident reports. Must concurrently serve in another volunteer role.
How To Apply
Interested in applying? Please complete our application form by October 30, 2026: https://forms.gle/sWBt8TZdKc3VgNgA9. Please also be prepared with a PDF file of your resume or CV.
Alternatively, you can send a message to [email protected] with the requested application information.
We plan to make our final decisions by December 2026, with meetings beginning mid-January 2027.
Eligibility
An amateur radio license OR a technical degree OR experience in digital communications is required to serve in any volunteer role.
Some roles may benefit from the following skills and experience:
- GAC, GET, and GCT – experience in K-12 education, university academics, research and development, and/or with nonprofits.
- GCT – writing experience is preferred, especially in scientific communications. Experience with web archiving is also of interest.
- TAC – experience using 44Net, as well as networking, development, internet regulatory matters, and/or related technologies.
We are always interested in volunteers who are located outside of the United States! A good command of the English language is important, and don’t let time zones deter you from applying. Our team works across multiple time zones, and we encourage interested volunteers from across the globe to apply.
Current and prospective grantees are also encouraged to apply. If you are involved in or could have a conflict of interest with a grant under discussion, you can simply recuse yourself from that particular vote or conversation. This allows you to contribute your time and expertise while helping ensure that our processes remain fair and transparent.
Terms, Time Commitment & Meetings
All five groups serve one-year terms that run from January through December, with a maximum of four consecutive terms.
Time commitments vary by committee and include both meetings and independent work:
- GAC – meets once a week for an hour, plus 3-6 hours a week for independent proposal review.
- TAC – meets once a month for an hour.
- GET – at the beginning of the year, this team meets once every two weeks for an hour, plus about 2-3 hours biweekly of independent work. After a few months, this is reduced to meeting once a month for an hour, with 2-4 hours of independent work ahead of each meeting.
- GCT – meets once every two weeks for an hour, plus 1-2 hours biweekly of independent work.
The time commitment for the CRC, which supports enforcement of our Code of Conduct, is anticipated to be very low. Because of this, CRC members must also participate in another ARDC volunteer activity. Applicants can indicate their interest in serving on the CRC when applying. We may also ask a small number of volunteers selected for another 2027 role to serve jointly on the CRC.
Additional Information
Questions about volunteering or the application process? Please reach out to [email protected]. Thank you for considering volunteering your time and expertise to support ARDC’s mission and vision. We look forward to receiving your application!
