Here are the top five social media happenings this week.

1. Instagram announces switch to algorithm-based timeline.

2. Speaking of algorithmic timelines, Twitter rolled out theirs as a default.

3. Samsung announces Waffle at SXSW – their own social media platform.

4. Everyone wanted a slice of Pi Day.

5. You can get paid to take a selfie.

Our favorite Instagram photo of the week comes from @adamdecker. He perfectly captured the green beauty of St. Helena, right in time for St. Patrick’s Day.

#365daysofwinecountry Day 7 … Sunrise Napa Valley…. looking down from #howellmountain towards the valley and @josephphelps winery below. The sun just peaking to light the clouds and light fog filling the low lands. Hey @josephphelps , “Apple maps has our location wrong”, found your sign by accident (while using @googlemaps ) except I meant to be right where I was. Beautiful estate you have. Cheers! #vineyard #vineyards #napa #napavalley #calistoga #sthelena #sunrise #100sunrises
