StumbleUpon

is a

free app for Android

that will help you

find websites that match your tastes

. Much like a late evening stumble after a trip to the pub, StumbleUpon can take you to strange and unexpected places full of magic and wonder (and

random Internet humor

).

The Flickr iPhone app makes it easy to

find your friends' Flickr photos

using a couple of different methods. You can do a general

photo search on Flickr

to

find photos

that relate to your chosen topic or you can

search through your contacts

or your own photo stream. Once you find what you're looking for you can

leave a comment, favorite that photo

or save them for later.

The best part about

using Flickr

is being able to view all of your friends' photos, which is why in this episode, we'll be showing you how to

browse your friends' albums

using the Flickr app for iPhone

. While viewing your friends' photos, you can also choose to favorite a photo or

comment on their photos

that you like.

If you're a Twitter maniac, then you might be looking for a quick way to

reply, retweet or favorite tweets from your iPhone

. Fortunately, Hootsuite provides just such a service making it easy to not only

view your Twitter feed

but also reply to interesting tweets. You can also

translate tweets to English

or to different languages, which makes for even more tweets to catch up on.

In addition to

creating bookmarks

for places in Gowalla, you can also choose to

add Gowalla highlights

. These are places that fit a particular description and happen to be your

favorite location

for that particular thing. Whether it's a walk in the park or a cup of coffee, these

highlight locations

can be shared with other Gowalla users so you can show them how much that spot means to you.
