Here are five technology things that happened in the past week and how they’re impacting your business. Did you miss them?

1 —Twitter is testing a co-tweeting feature.

Twitter has been confirmed to be testing a co-Tweet feature. The company’s social media consultant and mobile developer recently posted a test tweet showing both usernames above the content, though the new feature isn’t formally available yet. If and when the feature is officially rolled out, users will be able to send an invitation to “co-tweet” for other users to decline or accept. Accepted co-tweets appear on both users’ timelines.

Why this is important for your business:

An interesting feature for small businesses that are active on Twitter. Some uses: joint announcements with partners, joint press releases, joint messages from senior executives about your company. I look forward to trying this out.

2 — Now is the time to prepare for the Microsoft Excel macro crackdown.

Earlier this month, Microsoft announced its plans to revoke the decision to automatically block macros in Excel documents. Initially, the company said Excel files containing macros will be blocked if downloaded from the Internet. Microsoft still plans to move forward with blocking Excel documents with macros, but not in the near future. (Source: computer world)

Why this is important for your business:

Susan Bradley of Computerworld says now is the time to review your macro spreadsheets. “If you’ve downloaded something online and don’t know where they came from, stop,” she writes. “You should verify that they are not malicious by uploading the files to www.reverse.it or www.virustotal.com to see what the file contains.” Bradley says that “when you identify the Excel files with macros that you want to use (but that you didn’t develop yourself), your next step is to make sure that each of these Excel files doesn’t have “mark of the web” “on them.”

3 — Scammers blackmail US restaurants with one-star Google reviews.

Over the past week, several Michelin-starred restaurants across the country have been the target of blackmail. Scammers left multiple one-star ratings on Google for high-profile restaurants, then emailed the establishments requesting a $75 Google Play gift card in exchange for stopping the attacks. The reviews left by the scammers have since been removed by Google. (Source: Engadget)

Why this is important for your business:

You have to admire the ingenuity of the bad guys, right? This seems like a major headache for restaurants, but not as much of a threat as other malware like ransomware. I bet both Google and Yelp will step up their policies and procedures for identifying scam reviews and help businesses remove them as soon as possible.

4 — Tech startup Autumn launches a digital marketplace for death care.

A digital marketplace for bereavement has been launched by tech startup Autumn. The marketplace aims to connect grieving families with necessary services such as grief counselors, funeral homes, lawyers, appraisers, accountants, and other organizations that help families handle financial, legal, and various logistics after the death of a loved one.

Why this is important for your business:

According to Hospice News, fall is the latest entrant to a cottage industry emerging around end-of-life care and bereavement. A market research firm predicts that the nascent “death care” sector will be a $147.8 billion industry by 2026. If your company serves this market, this platform seems like something to consider.

5-Pinterest wants to be your shopping destination. Here’s how it makes it happen.

Last week, Pinterest launched a new set of tools designed to improve the site’s shopping experience for users. (Source: ZDNet)

Why this is important for your business:

The new tools — that also promise to create a more advanced experience for traders — include improved catalog management capabilities, product tagging on pints, the ability to add video to product catalogs, and improvements to the Store tab. Pinterest is doing its best to compete with Amazon, Etsy, and other online ecommerce platforms. It is a real alternative for companies that want to sell products online.
