App developer Gozaik says employers post 150,000 jobs per week on Twitter (TWTR), or about 15 per minute. That's a stunning total and might have some viewing the microblogger as a genuine threat to LinkedIn (LNKD.DL), Fool contributor Tim Beyers says in the following video.

Yet we've seen this before. Last year around this time, investors fled LinkedIn stock after Facebook introduced a jobs app in tandem with LinkedIn competitors BranchOut and Monster Worldwide.

What's happened since? LinkedIn stock has more than doubled as Monster Worldwide treads water. The company's Talent Solutions business also grew 62% last quarter alone. Signs suggest that LinkedIn is establishing entirely new rules for finding, recruiting, and hiring candidates. Sustainable growth and profits should follow, Tim argues.

Do you agree? Are you buying LinkedIn stock at current prices? What about Twitter stock? Please watch the video to get Tim's full take and then leave a comment to let us know what you think.
